Reencoded mp4

Hey guys,

i have a little tricky problem. I hope that someone knows this problem and how to solve it.

I’ve reencoded some mkv’s to mp4 to work on ATV. The reencode was done by Sorenson. All files had the same settings, h264, 5000 kbit for video, 256 kbit for audio, 720p.

Some movies works fine. But with two movies I have a big problem: When I try to play the movie, it seems that some frames are missing. It’s like the movie is freezing and playing and freezing and so on. But the mkv’s were encoded with framesettings: 1:1. So its not a PAL or NTSC problem.

Anyone know the problem and can help me to get this two movies working?
