Coreplayer does not convert the files, it just reads the avi's and plays them. DVD's on the other hand would take up too much room, they would have to be converted to a smaller compressed file. The program I use for this is DVD to Pocket PC.

Its not free, but it works good and the trial version will let you try it out to see if you like it.
I've never used it, but here's a free dvd converter/compressor.
