Just an update. no problems yet; keep moving multiple heroes episodes (~70mb/ea) on and off and watching them. One thing I have noticed is that I have yet to successfully install a program on it. I think I've only tried 2 tho. one of them was siriusWM5 which may not let you anyways, and I can't recall the other. The rest of the programs installed to my original 2gb which I copied onto the 4gb seem to work fine. I'm gonna try installing mobile live on it; I know that usually installs fine on normal cards and I can cache the maps to it which should give it a decent workout.
