I have been having a lot of audio/video out of sync problems as of late and cant figure out why. I am playing avi files encoded in xvid on my standalone divx DVD player. I am using Nero 8 Burning rom and ImgBurn to burn the avi files to a CD or DVD. I am using Sony CD-R and Sony DVD-R media. I have a Philips 8631 drive. I know these are problematic drives but it works very well for me. I actually just riped and burned a copy of Prison Break onto a Verbatim DVD+DL disc earlier and the copy works fine. I usually burn at 2.4X as I know that used to be the rule of thumb here and recently I hear more people say burn at half the rated disc speed but 2.4X as always served me well. Could this be why my data discs some times appear to have sync issue?
