Before I found this thread I decided I'd be interested in trying to TAS for the very first time. Here is my TAS ( very bad, but very good for a newbie, LOL! Is there an award for first time TASer? =D ) just doing Rockman 3:

The rom I used is titled "Rockman Mega World (Japan) (Alt).md" and the emulator was Gens-RR v11a (SVN 301). Please, any opinions and tips would be greatly appreciated. Before it is said, yes I did make a ton of mistakes and wasn't very persistent in some of the techniques I was doing, but what do you expect from a new guy like me? Hehe, this is a WIP of course, will be working on it on and off. Takes its toll on my fingers, but the end result was very awesome to watch.
Recorded my "prototype" run I guess you could call it for the lazy / non-Sega people, with XSplit, which is why it looks like crap. YouTube can't deal with stuff that is already encoded, fook dem!

I'm having that exact same problem. If I select NVIDIA GeForce GTX 260 in Graphics -> Select Device I get that error. When I leave it as the default "Primary Display Driver" the emulator is unable to scale up the window size, so I have to play it in 320x240, which is not cool at all. Wtf could have caused this? :/
I sure would like to try to TAS something for the first time, but with these problems it's impossible. >_>
