The problem with recording on my current setup is that the HDD in my current machine isn't very fast (or big) -- I should stick a real HDD in there at some point.
I don't know how practical it would be to do this during the normal session, but I want to get in some more games as we run up to NEC, so if you come by some other time (whenever it makes sense, if it ever does) then it wouldn't be a problem.
