I have d/l a TV show episode and it is on my HD in .avi format. When I play it on the computer (no conversion to DVD or anything else) there is a really bad sync issue, maybe literally 3-4 full seconds between visual and audio. Is it possible to screw up the sync if while the show is in d/l using another program? Problem is it can take 2+ days to d/l the 350MB file. Thoughts? Thanks.
