I think it's a basic lack of understanding of the CD burning process. Let's forget about burning DVDs at the moment.And bootable CDs & ISO images.
The average person deals with 2 types of CD burns:
1. AUDIO CDs
2. DATA CDs
AUDIO CD's are for burning 44.1x16bit wav files only.The Red Book spec for burning these CDs requires that only a single burn be allowed and that the CD is Finalized after the burn whether it be 1 song or 15.If you want standard CDs this is what you want.If you want MP3s you also burn them as Audio if you want them to play in a standard player. MP3 just let's you get more songs on a disc.
DATA CDs are just that. Data. It can be any file. Even wav files or MP3s BUT the wav files will not play in a standard CD player. They need to be opened by a program.Data CDs do not need to be finalized after a burn and can be written to again.
