You are very fast... faster then any payed support!
Yes, i read this Topic and i use a Sony Optiarc (i know it is a slimline but it is not a OEM drive ) with TDK DVD+R GOLD (I can only use TDK disc, my car navigator likes only TDK when it is self burned).
The firmware is up to date, or there are no newer version on optiarc site.
Have you any idea? It was not the first time that i burned the same iso in this burner. But it was befor i used the new version of windows and imgburn.
