[glocke12]

24" inch imac, purchased around 12/26/07. CD player does not appear to be recogniing HDCD's, but is playing most others ok. Any suggestions?

I don't know what to say. HDCDs are backwards compatible, they should work fine. Do they pop up on the desktop, or are they not even mounted at all?
