Same problem for me!
I am using windows 8 for the time being, so I don’t know if that might have something to do with it, but this really is not fun.
I have been trying all kinds of different combinations of things to get it to work, but it just wont. I keep getting the error “filter cannot report capture information”. The video either comes out really sped up, or the audio is really slowed down. They are never in sync with each other.
