I got a concert video that's split between two tracks. i'm trying to remove the end of one track and the beginning of the 2nd so they butt up against one another. i took the vob files in dvd shrink and made two new dvds, both of which i checked after editing and are perfectly in sync.

now when i import them into dvd-lab, demux them, link the two movies together so that one goes right into the next, and compile, the audio is out of sync.

any ideas what could cause this? same dolby 2.0 audio, same sampling rate, same everything.

thanks.
