There can issues during compression when you're going from a full range RGB image to a video legal YUV image as there's a luma shift and the YUV space is not capable of displaying all of the RGB colours. Codecs can cause hue shifts and in the past I've actually created an 'output LUT' to correct for certain codecs.
The thing with colour management you have to go through the whole process from input to output to isolate the reason for any unanticipated result that is your workflow or out in the real world.
Post some screen grabs.

I use an iMac I7- with raids... Maybe I can do an Layer above with an broadcast safe filter?

Most TV work to standardized delivery specifications, which your media looks as if it's exceeding. Because of delivery standards most TV add vibrance to the input, which does exactly what you're seeing here.
What broadcast safe effects are you applying with what settings?

I graded with the color board, as well as color finale just to put a little more punch in the picture. It seems really that the dvd pushes as well. Which it should not or? It should loose some quality. I burned a DVD and tested it on my samsung flat, with a BluRay Player which does an nice upscale. So the picture quality is just fine - and in standard picture mode it is too saturated and way to red. In "Film" Mode it looks fine. I know that every monitor and TV looks different BUT I presume at least if you sit down hours with color grading to get all even and set it right on the scopes it should at least look good! I don't presume that it should look equal on my grading but somewhere near. And I really don't wanna sit down again - getting the red out - so the dvd can push it in... this would be trial and error - horror on 45 minutes... thx. again to both on you .

With colour management it is important you at least start with a reliable datum and that means ensuring your grading monitor is calibrated and the OS is using the correct colour profile from the calibration process.
Can you confirm you do have a calibrated iMac screen and you've selected the correct colour profile? Are you using the latest iMac with wide gamut screen by any chance?
The talking head of the gentleman is very obviously warm as seen by the grabs and clearly measured in the scopes, his black tee-shirt shows a clear red lift in the blacks. The second pair of grabs are slightly cool which you can see with the curve line in the upper mid-tones is lifted in the blue channel.
I hoped you were going to post an fop grab and an iDVD grab. I don't know what to make of the screen shots other than the first grabs are very warm and the white balance looks off because the gentleman's skin is merging into the background. I'd certainly like to cool off his background to separate him and give the image a bit of depth from an aesthetic point of view.

So the setting was a warm setting in the itv - therefore I know that it is warmer that it would look like normally but I tried to grade it... and in fcpx it looks fine to me... the problem is the output... (there was another problem on the burned dvd with a frame or two sound delay, which is also awkward.)
BenB means that if I burn it DVD cuts off the blue highlights and therefore everything is darker and more red?
I didnt use any safe standards yet... it was a question if I apply one everything will turn better/ or worse?
It is a DVD but not for Broadcast... and last but not least... nope no calibrated monitor it is an iMac! I know that this is not the best monitor to do this things - BUT if I cut and edit on the same monitor that I playback - it should look always the same... and it doesn't matter if its calibrated or not because red is always the same red on the same monitor right? Too easy to say its the monitor... if that you shouldn't use an iMac at all... too bright too colorful too everything... but thats what I got... thanks again...

I'd definitely apply a broadcast safe filter to the footage, and while I don't have anything to do with broadcast, I'm sure that some other members that do could explain it's proper use, and what to do to the color grade before and/or after applying it, or you could search the forum for more info.

Your RGB parade is showing several things.
1 You are crushing Blacks (dark/shadows) You could raise the exposure and readjust the mids.
2 The super whites is due to the light fixture to the right of subject. Apply a shape mask in the Color Correction and reduce exposure inside the mask, you could also reduce some color or saturation inside the mask as well. Goal is to knock down the overexposure due to the light. This gives you more room to correct the rest of the area.
3 Reds are too high, mostly showing up in the face/skin tones. Try reducing the mid tones red. Changing the saturation levels will help and then it is just finessing back and forth.
If you have more clips from same camera shoot/set, you can create a custom preset and apply it to the other clips to correct them and keep a consistent look.
Hope you do realize that RGB parade along with some of the other scopes represent spatially the clip. You can clearly see the shoulder, hair/face and the light as you go left to right.
DVD is a 20+ year old "standard" that creates abilities and limitations on optical disk delivery. This includes not only file formats/structures, but also data bandwidth, maximum delivery speed, and resolution/ratios. The various disk players also have to interpret and convert to screen the video. Upscaling by a player will most likely change the original images.
Combine this with different versions of DVD "standards" used by different manufactures and "allowable" exceptions to those standards, there really is only a general "idea" of DVD, not total conformance.
Apple with iDVD uses allowable non conformance. Apple version of HD 16X9.
Finally, when you exceed the DVD standards in the video side, it affects the audio side too. Normally audio static/distortion. This relates to how many bits can be stored and read on a DVD and is one reason why Blu-ray is so much better.
Hope this helps, Greg

Secondly, even though you are not going to broadcast, you should still grade your DVD to be broadcast compliant with respect to legal video and audio levels. If you find your finished color corrections still leave a few over the limit levels on some clips, then a broadcast safe luma filter and/or chroma filter should be placed in the project. This can be done on an adjustment layer to span whatever clips need them, or individually per clip.

I totally agree with you that Optical disc in general and DVDs in particular are still distribution method of choice for lots of folks. I help families and groups produce "Family" movies that are scripted, costumed and often feature length. These are then mostly delivered by DVDs ~(80-90%) BDs ~(10-20%) and a small number via USB stick and only occasionally electronic or streaming via a service. So still have to "burn" discs.
I lament the lack of support for iDVD which is now only partially functional in El Capitan. Still the best simple but nice authoring program for DVDs.
Blu-ray can be burned on Macs, but Apple support of BD is very limited. If you export out of FCPX as a BD disc, you can right click the .img file and burn on a supported BD R/W drive.
Creating USB sticks have issues all their own. Streaming while a very real possibility and perhaps the most universal, is rarely wanted in what I do. People just seem to want a tangible disc to put on the shelf. I'm still burning 100s every year.
Dan's (dgwvideo) advice about using multiple color corrections for various corrections is a good one. I routinely do this.
Not sure when you talk about using an "adjustment" layer if you mean just addition levels of color corrections, or did you mean using an actual "Adjustment Layer" in the Timeline and applying Color Correction and Broadcast Safe filter to that. ??
An Adjustment Layer is in essence an empty Title clip that you can add filters or correction to and it affects all layers below it in the Timeline.
I have applied Broadcast Safe (BS) filters to the entire Timeline via an Adjustment Layer so I could make new adjustments to Color Corrections and being able to turn BS on and off. I ran into some issues doing it this way and mean to pose the question here at some point.
What I found in the project I was doing was that when I applied the BS filter to the entire Timeline via an Adjustment Layer, the various clips responded differently. It seemed to aggregate the amount of filtering to the greatest level of any one clip in the Timeline to all clips, in at least some of the clips, instead of only applying a minimum amount of compression to each clip. BS is in essence a compression algorithm to prevent super whites and blacks.
I have not figured out if this was due to some of the plug-ins I was using or if it is intrinsic to how Apple wrote the BS Filter. If I viewed the same clip in the scopes when BS was applied to the entire Timeline via an AL the compression or dynamic range would be squashed more than if I applied the BS Filter to the individual clip. YMMV so proceed with caution.
Anyone else notice this?
The one thing I would say about BS Filters is that it is important to do Color Corrections first and then the BS as a safety feature. Don't use it for an easy shortcut for CC.
I burn both DVD and BD test discs and then view them on a couple of TV/monitors and verify the quality of the disc. This leads to a couple of revisions at least till I am happy with them. The disc will also look different on different TVs/players.
I always "Share" export the DVD/BD file to the desktop and "Burn" the .img from there and don't use the direct burning inside of FCPX. Less problems, and you can also then make(burn) extra copies without opening up FCPX and re-export.
If you use iDVD, then you want a QT or .mov file instead from FCPX. (there are additional file formats supported by iDVD, my point here is that iDVD will create the disc image file with the needed support file structure for DVDs )
Lots of great free tutorials on Color Grading on the internet, well worth the time to watch.
Here's a link to Denver Riddle's channel which has good videos… www.youtube.com/channel/UCAYVd0fXmRJFkBAaQJRvcuw
Happy Editing, have fun
Hope this helps, Greg

thanks again! I know the difference of these to possibilities of grading. I got into this with Dever Riddle and Color Finale and watched a lot of tutorials and moreover graded a lot. I do also weddings and these I shoot always in Cinestyle so I have to grade a lot - but good practice... This work was shot in a modified standard look (canons) to match the 2 cams... so there was just to pop a little the colors and also blacks... I know I tend to crush them a little...
again thank u and yes greg... I love idvd.. because u can create fast a nice menu while adobes encore (for blu ray) is horrible complicated to work with and u have to include ae for the menus... sadly apple has tossed away the pro version and doesn't care about dvd´s in general...
oh greg: how do u create a preset that u mentioned? I always copy and paste (part) of the effects... a preset would be really fine... (moreover for the dvd output)
cheers
