I've had my Pioneer DVR-109 for over a year now, have it installed in an external casing, and connect it to my laptop through firewire. Until now i have had no problems. Today i tried to make a backup copy of a dvd i own and the burn process (alcohol 120) would start and after a few percent complete, the burn speed would slow down to zero. After about 15 minutes the drive will produce a write fail error (sometimes something about sense information, sometimes about simply timing out) and just stop. I tried using Nero and DVD Decrypter with similar results, the burns would just STOP. I've never had problems like this before and I have no idea how to fix it. Please help me out if you can. Thanks a lot in advance guys.
