I have just acquired a Pioneer 108 and am having a lot of grief. First of all it wouldn't read any data CDs or DVDs and wouldn't play music CDs or movie DVDs. I sent the thing back and the replacement suffered from exactly the same problems. It also wouldn't execute and CD based software and wouldn't autorun. I eventually got it working by disconnecting the slave device, which was a Zip drive. However, I still have a problem, I only get sound from CDs. If I play a DVD, I get the pictures but no sound. PLEASE! (before I go mad) does anyone have a clue as to what is wrong?
