I have successfully converted about 2 hours of analog, 8mm tape to DVD using Sonic My DVD ver. 4.5. (1hr/dvd). When trying to conver the next hour's worth, it would not let me build a file any longer than about 25 minutes even though it said it recorded about 60 minutes. I previewed the video in with the editor function, and there ws definitely much less than 1 hr. Any ideas - everything had been working fine? I noticed that the video projects are in C:../My Documents/My DVD's. Is there a limit to that folder size? I wouldn't think so.
