I'd give fraps a shot, you can get a free version which has no lifespan, just some limitations. If the free version works, then the paid version, which is $37 with free updates, should work.
I have the paid version, and honestly I've had issues recently, so I find it difficult to recommend, but can't hurt to try it out yourself. In the past I always had great performance out of it, even in graphically intensive online environments. In fact, as recently as the D3 release, fraps was fine for me. Just now I don't know what is going on.teahousemoon2012-09-27 03:58:52
