Been working on Macs and PC's since the 1980's, been editing videos professionally since 1981.
I am not a neophyte.
Last time I looked it looked like an Intel Processor to me... then again maybe I'm wrong.
The MCE 12x drive is two years old, it has the last firmware update available from the manufacturer.
I've read online where someone said that I could downgrade QT 7.7 to 7.6 and that when 7.6 was upgraded to 7.7 that it caused Toast 10 to no longer burn BluRay data discs. They provided a link to where I could, if I wanted, downgrade my QT version to an earlier version without reinstalling the OS and they said it worked fine.
I have not tried that.
From your response, it sounds like you think I got my facts screwed up about my system, or the Toast software.
Not.
If you go to this link, you can read what I've been going through with the help of another Mac professional with no joy as the end result.

Like I said there, this isn't rocket science... I have all the minimum requirements necessary for Toast 10 Titanium to function correctly but it doesn't. How you got yours to work is a mystery but I am not the only one who has had issues with the disc burning app.
