Interesting. Can you tell me if strange frame skips or duplicates
happen at the beginning (with or without pullup loaded). Unfortunately
mencoder doesn't like filters that buffer a few frames ahead, so
pullup has to do a nasty hack to hide that it's doing this.. If the
first few frames are supposed to be skipped it could mess things up
rather badly, perhaps...?
