"A primer on CDFS, which I'd never heard of until your post. Best option would probably be to rip the files then burn them to a CD-R unless I am reading this wrong."
He's right. Try that next. But make sure you tell your burning software to make a music CD. That way your CD meets all Redbook standards, and it will be compatible.
If that doesn't work, try transcoding the files to something more common like FLAC or WAV. If you can get them to convert, you should have no problem burning the cd from the transcoded files.
