|Assuming you meant DVD, not CD....if you want to keep them as .AVI's, just burn as a data disc. As kuwese pointed out, you should be able to fit 5-6 videos on a single DVD. They will NOT be playable on a standard DVD player though, unless the player supports DivX or DivX Ultra.|
I use DeepBurner for creating discs with multiple AVI's:
If you want to convert the AVI files to be compatible with standard DVD players, you *should* be able to get 2 videos per DVD. Re-encoding for DVD playback can take hours though, depending on your system specs. For that I use ConvertXtoDVD.
