Can VDR handle two different types of DVB card at once? I've got two different makes of DVB-T card at the moment, which is fine because they share one channels.conf, but I'm thinking of replacing one with DVB-S for HD. Can VDR assign a different channels.conf to each card and merge the channels list for the EPG?

For what you need different channels.conf files?
You can use same channels.conf with combination of many different DVB-adapters. Source -field in channels.conf determines from which source the transmission is coming from.

So it would scan both cards and save the results in one file? And where both cards have the same channel, eg "BBC ONE", there would be two entries for it? Would two copies show up in the EPG and would it indicate which card each is associated with?
Sorry for all the ?s.

Everything looks and acts like with your current configuration with two DVB-T adapters..
If you have BBC ONE from two different sources (T and S for example), you would have 2 entries in your channels list. You don't know which one comes from which source without patching or looking through channels edit -menu.
About scanning i have no idea, i've myself always made lists manually.

Nice theory, but ti doesn't work in practice for me. With just the DVB-T channels in channels.conf (I haven't got the DVB-S card working yet) and the DVB-S card present I get "Channel unavailable" on every single channel. Without the DVB-S card present VDR can use the DVB-T card.
Could it be a clash because both cards have a Philips SAA7146 chip (they're both Hauppauge WinTV Nova PCI models)? If so, this problem only arises if you try to open both cards at once, or it's unique to VDR, because other dvb utils such as scan, tzap and dvbstream do work on the DVB-T card when the DVB-S card is present.

OK, it seems that it was the problem with the DVB-S card that was blocking the DVB-T card too. Once I got the right module installed for the DVB-S's frontend VDR could use the DVB-T card properly.
Can you explain it more. What is "the right module" ? I have 2 dvb card, one nova-s and one nova-t. with szap i can use my nova-t. With vdr no success, i have "unavailable channel" when i switch to dvb-t channel. Plz help...

For the Nova-S I hadn't built the stv0299 module at first, and then it wasn't installed after I thought I'd built a new kernel because recent versions of make-kpkg don't seem to automatically rebuild after changing something unless you delete its stamp files first.
For the Nova-T the front-end requires tda1004x and also a firmware file called dvb-fe-tda10045.fw; /usr/src/linux/Documentation/dvb contains a script to fetch it. If you haven't installed the firmware you'll get the "Channel unavailable" message as above, and you'll also see "tda1004x: firmware upload failed" in dmesg.
This depends on the model; some Nova-Ts have a completely different chipset, usually cx88 I think. I had another card which used that, it also needs some analog v4l drivers before the DVB drivers can be enabled. I'm not using it ATM because I've only got 2 PCI slots.
The modules the Nova-T and Nova-S are using between them are:
stv0299 tda1004x budget_ci budget_core saa7146 ttpci_eeprom ir_common dvb_core
You can add both the dvb-t and dvb-s channels to same channel.conf. VDR is smart enough to recognize for which channels it needs to use dvb-t and for which it needs to use dvb-s card.
I am currenlty for example using hvr-1300 (dvb-t) and hvr-4000 (dvb-s) just fine with vdr-1.6.0.
