This looks like an old old thread. HOWEVER! I just purchase VP v8.39. And guess what? I have a 10-screen multiview. And I've tried several export formats. I always get one of the 10 clips/screens that never moves. Frozen from the start. This is best-case. Other formats (MP4) freeze/skip more of the windows. Is there something i can do? I mean after 3 1/2 years of this problem, and 3 new releases, this should be fixed. No?
