Hello,

i downgraded kernel to 2.6.23.17 since my report (problems only related
to nvidia driver).

i tried "v4l2-ctl -D" on the two devices provided (/dev/vide0
and /dev/video1) by the card but i got no error messages. i had to use
commands like "v4l2-ctl -s SECAM" to have writereg errors but i already
know that this is not supported with 2.6.23.X kernels. dvb works fine
after theses calls. I also noticed that "firmware loading successfull"
message did not appear correctly when i used hal 0.5.11 rc2. maybe hal
prevent the firmware to be loaded... i just tried hal to 0.5.11-1 and
same problem occurs.

I next stopped hal, unloaded cx88XX drivers, reloaded drivers,
downgraded hal (restarted by aptitude), dvb (Hauppauge HVR 1300) works
again.
