How to burn a Blu Ray dis

Hello guys, I'm new in fcp.co and I need your help. I need to record a 1h and 30 min project to a BD-R burner Sony VBD-MA1. I'm running a FCP X 10.2, Compressor 4.2, Roxio Toast 14.1. This is the audio file I got from compressor (Dolby Digital.ac3) & video file (Blu-ray.264). Why is not working. Please help.

not sure if you meant to send an audio file or not, but i'm not seeing one.

Also, are you trying to just burn a quick Blu-ray? Or are you mastering one with a decked out menu and stuff?

You can just use the 'Share' option in FCPX to burn your project directly to a Blu-ray
