Hi,

I have Problem's with the H Polarization on my Hauppauge Nexus DVB.
all other Feature work very fine also the lirc from the Card... but
when i switch to a Channel with H Polarization i get no Picture.
I have bough me a Sat-finder which shows the voltage and tone signal
and this is fine ... so I have install Win 2000 and the orig. Driver
from Hauppauge on a second Partition and every thing goes fine.
So it is not a Hardware Problem.
The next step was: checking the Voltage with windows driver and with
Linux driver :
Linux DVB Driver V Polarization 13.5 Volt
Linux DVB Driver H Polarization 19.5 Volt

The DiSEqC spec defines 13.0 and 18.0 volt to switch LNB polarisation, so these values should be fine.

W2k Hauppauge Driver V Polarization 15,8 Volt
W2k Hauppauge Driver H Polarization 22,0 Volt

I don't know how they do it, please report if you find out any details, then we would be able to implement the high-power ioctl for these cards...
