audio synch problems when backing up episodes with nero

[emored]

had some divx - avi episodes on the drive and i have burned a few off to dvds and noticed a lot of these seem to go out of synch after a few minutes , all i did was simply copy them as data to a dvd and played them on the yamada , is there any reason this method of back up would cause problems of a synch nature ?

advice appreciated

does they work fine on your computer?

and you aren't doing any video conversion so I'm moving you.

hope this reply reaches you as you moved it ? anyway yes that was something i meant to include in my post , they do seem to work ok on the hard drive thats what is hard to figure out , al li did was a simple data copy using nero .
