I'm using an IVC-200G which is a 4 port capture card. Its only composite
so the quality isn't as good as an Osprey but it works well with both
AG1 and 2 as long as you have the latest bttv drivers. I'm using a 2.6.4
kernel as I couln't mamane to patch an earlier kernel.
I've got an osprey in the same machine and it doesn't give any trouble.
Cant get the balanced audio to work though :-<.
The UK supplier for the IVC card is wordsworth.co.uk.
