Oh, I did a quick google search, I didn't really read all through it. But its a place to start I guess. I use DVD flick, i know it used multi thread, but whether cuda or not, is unknown to me.
It is the one you can mess around with the most, for cpu cores or cuda cards, but it 'can' take a bit of getting used to, depending on how deep into it you want to go.
EDIT: their commercial product is called MediaCoder NT Cuda Edition - that's not the one you want to download as it does pretty much the same thing as all the ones in the review link a few posts back.
So even the standard edition doesn't do it either? Doesn't look like it burns.
From what I've been able to work out so far is that while some of the major programs don't support it properly at all for what I want, the odd couple do.
The closest I've gone to it is PowerDirector 9 which does allow you to transcode and burn with CUDA but only on the AVCHD format disc rather than DVD.
Argh, can't believe this is the second time I've recommended MediaCoder to someone wanting to transcode using cuda AND burn to DVD.
No, it doesn't burn. (I'll repeat that to myself a few times in hope it'll sink in) I don't think it would even setup the VIDEO folder for you, just transcode the movie into the correct mpg format.
