PS2 Reality Player question

[Slippery Pete]

So I have been searching for the last little bit with not much luck.

Can you tell me anything about playing movies in the PS2 that are avi or mpeg format burned onto a cdr? That is mainly what I want to do. I have a VCD player but I find tha quality too poor for my taste. Someone told me that I could play the actual avi or mpeg file if I modded my PS2...
