No, I have not tried the video4linux drivers, but I think I may now.  I 
compiled the ivtv drivers from source as they don't supply binaries, so 
I would've thought it'd be a piece of cake.

This brings up another question though.  The V4L module is included 
with the kernel and I enabled it when I built the kernel.  Does this 
mean that the V4L module in my kernel is not new enough?  I think I 
read it was just starting to be included now that I think about it.

Many thanks!
