[vdr] Re: Two tv's connected to one vdr-mashine

["Matthias Raus" <matthias-raus_vdr@web.de>]

Hi! 
 
this is exactly what I am planning, too. I want to run two DVB-cards in the same PC and watch 
different channels on either of the cards. I have found out that some people already have realized 
this. Obviously, it is only necessary to load the DVB driver once and after that start two instances 
of vdr with VDR1 and VDR2 using different video- and config-directories. A person working at the 
heise magazine has written a runvdr-script for three vdr-instances; I have modified this a bit in 
order to work with only 2 instances, but I don't if it will work yet. Could anyone of you look over it 
and tell me if this will work that way? I also don't understand what the "Endlos-Schleife" does 
exactly, as I am not a script-guru...here is the code, thank you in advance:
