I have an Athlon 850.
I started with 30 fps but the capture never started.
When I turned it down to 15-25 fps it will run, but as I said
It creates broken files as far as mplayer is concerned. I can try other
players and provide files if there's interest. This is all from
antennae source on the bt848. I can try video and s-video too.
