I'm kind of in a rush right now.

I didnt have time to read your whole email, but I just need to point
out that your method is flawed.

#1, as i think I already stated in my previous email, you *need* to
use the v4l-dvb mercurial repository if you want the FusionHDTV7 to
work.

#2, if you are passing card=4, then THAT is why it is not working.
FusionHDTV7 is *not* card 4.  Dont pass anything, let it autodetect.

Good Luck,

Mike
