I have upgraded my Toshiba Satellite Pro M 70 from Windows XP to Windows Vista Ultimate. Everything seems to work except the recording process of my DVD drive. I have a Matshita UJ-841S. I can read DVDs and CDs fine but I cannot record anything. Whenever I try to record (and I tried lots of different software) I get the message that there is no media insterted in my drive. I also tried different DVD brands but no difference. I searched for Vista drivers for Toshiba but I cant find them anywhere. Can anyone help?
