Burning a DVD problem!!

Hi everyone,

This issue has me stumped. I have a couple of .avi files that I am trying to burn to a DVD (the info is about 2.2GB). However, no matter if I use Tiger's burn folder or Toast Titanium, the DVD won't read on either a Mac or a PC. On the burn folder it just won't read and in Toast Titanium, it says that the burn won't verify.

Does anyone have any idea why I can't burn data to a DVD? Thanks for your help.
