I tried SEARCHing for any threads about this but wasn't successful.. Pardon me if I overlooked anything, I'm new.. I was following this procedure to burn my first multisession cd (I've only burned cd's in my iBook using iTunes before) but I didn't know what IMAGE FORMAT to use when saving an image (I meant to burn a data cd). Can someone plz explain the differences of the ff: 1. read-only 2. compressed ------------------- 3. read/write 4. DVD/CD Master Thanx!
