[pvrusb2] Fuzzy Video using Hauppauge WinTV PVR USB2

[cardboil]

Another test:

I tuned to a channel via ptune-ui.pl.  Then, I viewed the output via mplayer
using "mplayer -vo xv /dev/video0".  mplayer shuts down with the following
error (another ininstance of Xvideo error):

It seems there is no Xvideo support for your video card available.
Run 'xvinfo' to verify its Xv support and read DOCS/HTML/en/video.html#xv!
See 'mplayer -vo help' for other (non-xv) video out drivers. Try -vo x11
