Sound out of sync

[ssaamm]

I download my films of the internet as avi files. I then use DVD flick to create chapters and a menu screen. I then use IMGBURN to burn the files onto a disk. The film play fine on my DVD player, however the sound is ever so slightly out of sync with the rest of the film. This has happened to all the films i have burned. Any ideas on what im doing wrong?

PS i am using verbatim disks.

Are the burned dvds also out of sync on your computer using a software dvd player?

I would probably try another converter and see how it works, like if you want free ones you can try favc, avstodvd, thefilmmachine or trialware like convertxtodvd.
