I have an other problem. I have to start VDR with ./vdr several
times, because it often crashes during start with a segmentation
fault.
If vdr is running I can't switch channels. (Only the OSD displays
the channel to which should be switched, but vdr doesn't switch)

If I press the OK button for the Info-OSD I get these tech-values:
0dBm [         ] - snr 134.0dB

If I select the tech-page of the OSD-menu I get these values:
SS:  [.            ] 5% - 15dBm
SNR: {xxxxxxxxxxxx} n/a -  134.0dB

I have tried it with siemens_dvb-0.9.4-2002-05-20.
Once with the vanilla version of the driver and once patched
with http://www.mallorn.de/dvb-stv0299-signal.diff.gz
but there is no change between this two versions.

I use a Hauppauge DVB-c card with QAM_256.


If the start of the tech-patched vdr ends in a seg-fault I
get this log:

If the start of the tech-patched vdr without a seg-fault I
get this log:

Behalf of "ERROR: attempt to set channel with unknown DVB frontend type"
I tried to set the frontend type hardcoded, so I added in dvbapi.c
in line ~3318 before the switch statement:
frontendTypt=FE_QAM;

But with this change I get always the segmentation fault if I try
to start vdr.

I am interrested in every tip, comment, remark,...
