It's possible that it might be small glitches in the playback that your PC/Mac video players are smart enough to overlook or repair on the fly, but that the PSP just stops dead cold when it hits them.
Try using a video conversion program to re-compile the video and see if that helps.
At least 3.71 has sceneskip in videos now, so this problem is less of an annoyance than it might have been in previous firmwares!
