Sense codes are almost always hardware. Check to be sure you have up to date firmware.
I understand the bluray worked.
Create a new DVD, and see if you get the same error,.
It is crazy as I can burn a single video on the DVD but more videos will not work! I hooked up a new external burner it worked randomly as few copies were corrupted. I did copied the DVD iso onto my PC and burned few copies and again few did not work as I now suspense the combination of bad batch of Memorex DVD and a bad internal DVD drive. That is my guess! Anyone?
