I'm using xsplit Personman. What made me get much better picture quality was View -> Resolution -> 1280x720, did you do that? If so, I have no idea. I was unhappy with it the first time I tried it out, but after changing that setting, I think xsplit rocks.
Nice to have someone comment on the gameplay
I won't try to justify it, I think not being used to thinking and talking (in English, mind you) at the same time made me play kinda bad, definitely seems like it takes some experience. Looking back on it, it's pretty obviously a huge huge mistake, and one I don't think I'd make under normal cirumstances. I think it stems from a misunderstanding of what my deck wants to do at that point; I'm basically aiming for a megaturn with playing 3 crossroads + Horse Traders, drawing a billion cards and being able to buy 2 Duchies or a Province or something. In reality, what I need is, like you say, to consistently get to $5, and probably shouldn't be aiming for the megaturns.
I knew I'd play that game really badly when I chose the strategy on turn 1, which I thought was a very real reason not to go for it heh. Oh well, playing bad and being called on it is a good way to not play as bad next time I guess.
