Is it possible to burn CD-Audio onto a DVD, in the fashion that a DVD player would read it as a CD audio disc? i.e. use CD TOC and whatnot...?
I'm pretty sure that would violate the Red Book specification for audio CDs. Not 100% sure though, wait for someone else who knows more about this.
No, it's not possible.
DVD-/+R(W) discs cannot be burned as CD discs and they will never be identified by DVD players "like" or as CD discs.
