And yes i was using cheap media because as I was just startin out i did not want to make expensive frisbies! That said the two I did burn produced good quality films.
Also, when i was burning, i was online and i now suspect that either ms or antivirus did one of their "magical" updates during the burn proceedings to mess me up

I also read other forums and checked;
dma is on if availble on primary and secondary devices.
Imapi is stopped and manual in "services.msc" (re someone elses forum or threads)

hope this helps you to help me
thanks
