Re: FCP X playback problem when updated to Lion

The playback problem is that it's is drooping frame, the time in the dashboard it slow and skip frames, the material looks like it have a strobe FX. When I export the video as ProRes it's look perfect in quicktime, so it's a problem inside FCP X.

I am editing 3 TV spot 1 x 30ss 2 x 15ss , the material was recorder with Canon 5D 1920x1080 29.97p, I begin editing with FCP X 10.0.5 in Snow Leopard Mac OS X 10.6.8 with the original material but it was kind of hard for the machine so then I convert the material to ProRes and the material play perfect. The past thursday june 28 I purchase Lion because I want to istall the latest version of AJA software so I have broadcast monitor and it require Lion. Friday I edited a 720x486 project with no playback problem, Yesterday I return to my 1920x1080 29.97p project and that's when I notice my playback problem. I try playback with high quality and better performance and also try proxy with same results.
