Do you have only one Koax-cable from LNB to your room?
If two, you do only need a "multi switch".


If one koax only:

There is only "one" problem (i think i wrote already several weeks ago?)

VDR "forgots" to turn used cards off, or at least turn it
back to vertical polarizition.

So it is not possible to record or see(!) any vertically polarized
programs, after VDR recorded one horizontal :-(

Workarround:
Programm after each hor-recording a vert-recording and 
keep fingers off while vert-recordings...


I never heard about any patch that "locks" the VDR to "vertical"
if "vertical" is recorded.


On "horizontal" there is no problem: One can't switch the
antenna to "vert", be cause the highest Voltage wins.
And that is these for hor polarization.

DeSeq etc. is not possible AFAIK.


Manually you can force the second card back to horizontal
if you start a recoding manually, switch to an other
channel, switch back and stop the recording.
