Only, I don't think it needs to convert anything back to MP3 format. It's just making a copy in memory to burn the CD and then discards it. I think it's in the Temp folder somewhere. Same place DiscBurner probably puts your burn when its copying files. (I think?)
Dude, so what's with the 4 systems! Geez, I'd like to have that kinda setup, only with my G4 Dual450, ang get a a Ti and a new Dual733(superdrive and all) I wouldn't leave the house. Well, at least not the yard, since I'd have airport like you all around and could wander.
