CD-R Media Types and the JVC XL-R5000BK Component

i recently got a JVC XL-R5000BK component unit ... only i'm having
trouble actually finding CD-R media that it works with ... most media
i've tried fails with the unit coming back saying that their is "NO
AUDIO DISC" ... anyone have this unit or a similar one?  the only thing
I've been able to get working with it was some old media from a year or
so ago (which i've used up) which came from CompUSA and claimed to be
specifically for AUDIO recording.  It's weird because I'ved never had a
problem working on my PC with my HP CD-R recording music on ANY type of
media, really.

any help woudl be appreciated.

thanks
