regarding to:
But AFAICS unfortunately no gigabit Ethernet (which I'd like have in order to record to my server).
[..]
I don't want to lose the ability to record 3 DVB-S transponders in parallel, and I also need the DVB-T card.
hmm, may i suggest to stick two of your DVB-S cards into the server and only keep one for live viewing? this would most likly increase the chance of getting better client - server integration into vdr as well. ;-) we users of a client server setup like that, have to jump through hoops regularily, ' cause of vdr's lack for real multi-frontend support.
