Hmm i don't really want a program with spyware. I had spyware probs with kazaa a while back. It's not as bad as that is it?
As for the codec i've found that i have had avi's before and have had trouble with lip-sync problems when watching on a standalone dvd player. I think it was something to do with NTSC/PAL.
DivX always seem to work fine.
Whats the diff between DivX and XviD?
Sorry if i sound really dumb, but i'm getting interested in all this now and wanna learn more, hehe.
Gotta start somewhere i suppose!
