I can reproduce following:

vdr can record from senders on V polarisation like sat1, prosieben ...
even without reloading the driver.
vdr can not record from any sender on H polarisation like ard, zdf ...
even with reloading the driver it doesn't work.
This explains, that I got some recording and some not.

Does anybody know what can be the different between H and V polarisation ?
