Oh, ok. I downloaded the latest source of ivtv and compiled and
installed it. So I'm assuming I have the latest version. But I'll see
if I can find out for certain.

I know on the command line I can use -vo xv and it works fine. The
only problem is that it displays it to my /dev/fb0 device instead of
/dev/fb1. So when I use that it displays it to my PC monitor. How do I
get it to use -vo xv but instead to send it to my /dev/fb1 device (the
PVR350 output) instead?

OK, I'll search the list for those.
