answering Peter's question from a pc point of view?
I have 3 thoughts to add
1} I think, in his case, it maybe the 3d setting of the graph card, if his frame is 10 fps and above for a video 1032 x 774.

2) or he may not have the right video grabber or using the right movie format for getting a constant 10fps and above.

3) or if its random and drop frame when he records
his machine maybe doing things in the background
