I tried 12.5.1 (free) without quicktime and it doesn't seem to see mp4 files, at all. 12.5 works flawlessly, (with quicktime). 'Can it be an amd cpu issue? (Something to do wth the instruction set.) I haven't tried 12.5.1 with quicktime, yet. Does anyone have the same issue?
Thanks, missed that. Though I haven't had any problems with 12.5 on win7. I haven't done any major projects. But with version 12, I finished an hour long HD video for a play, that I was working on for months, without any problems.
