BTTV/BT878 Woes - The wicked Dragon rears it's Head again

Thanks for the info. I will check when I get home.

I am wondering about v4l2: is it in the kernel, like v4l, or how do I 
implement it? I am definitely using v4l, not 2. I have put an entry into the 
xorg.conf to load the v4l module. Is this how I would load v4l2? Anything 
else I need to do?

Is v4l2 preferred? I see very little mention of it and it appears, looking 
at the bytesex site, to be somewhat a deviant or dead development line, or 
am I mistaken?
