The attached oneline patch causes dvb device 0 to look like a card with 
unknown frontend type, so VDR shouln't know how to use it. Untested.

Perfect - both that and the 'If(PrimaryDevice) hacks pointed to by Patrick 
work like a charm for FTA chans, so I'm happy until I can get another FF card 
=)

Cheers,

Like I mentioned befora, I'm having the same kind of problem. My primary
card (Fujitsu-Siemens DVB-C) doesn't receive QAM128 channels at
particular frequencies very well but I'd like to keep it because of the
quality RGB output.

Tried both of these hacks to disable it's use as a receiver but with a
disapppointment. Both of them cause ARM crashes/errors on the primary
card (otherwise, the funtional part works ok and as expected):

dvb-ttpci: __av7110_send_fw_cmd(): timeout waiting for COMMAND idle
dvb-ttpci: av7110_send_fw_cmd(): av7110_send_fw_cmd error -110
dvb-ttpci: av7110_fw_cmd error -110

and so on..

The "dvbdevice-avoid-0.diff" also makes channel changing untolerably
slow but then again, it was untested and something like this could be
expected.
