I have been burning CD's for what seems like forever. And since getting a new PC with XP this past november, I have simply been using the WinMedia software to convert and burn in one easy stroke..until now! The last coupla times I did this..the CD's are unplayable in my Kenwood 200 disc changer AND show up as No Disc or VCD in my RCA DVD player! I thought it might be the brand of disc I was using..Imation..because in the CD recorder I have..commercial uses ANY blank CD format..the burned disc show as No Disc..BUT after displaying that message...the tracks and time show!?!?! Anyhow..putting in a blank Imation disc...the recorder recognises that JUST fine. Now..here is the kicker.... These play JUST fine in my older players!!! My Pioneer CLD-704 and nearly 10 year old Pioneer 100 Disc player as well as my Apex AD-600A. For the record I tried re-burning these using Sonic Stage that came with my Vaio...no better. And neither program will tell me if it's a CDR or CDRW and offers no option to "Close" a disc on my own..in case that had not occurred. Any ideas as to what might have changed with the burning/converting software?
