I have used the DP-24 to burn CD-RW's successfully. The trouble is, I can't seem to successfully re-use them. I've done an erase using the DP-24 but it doesn't seem to work. I've even done an erase using Windows 7, which seems to work fine, but the DP-24 still won't use the erased CD. I get an error message, "No room on CD etc..." Has anybody had better success? Thanks - Bill
