[QUOTE=mciahel;2247628]Hi and Welcome!
your issue is probably not firmware related.
Please try if you can read already recorded and factory pressed DVD discs.
You might also try the unit with another computer in order to rule out issues with your Windows installation.
Thanks for anwering,now I remember,I inserted a cd instead of a dvd and
started burning.I guess I damaged the unit.What you think?I tried to play a
dvd and no response.I guess I FRIED.
