CDRECORD.EXE will burn 2 sessions but i cant make .cdi from burned backup

CDRECORD.EXE from Echelon will burn two sessions, so I figure that means my cd-burner is multisession compliant, but when I try to make a .cdi from a burned backup, I mean it makes a .cdi but if you burn from the new image, the disc comes up as Audio CD on DC. Is there a fix.
I'm not new to burning at all. I just need to make .cdi 's from already burned discs for ###.
