 bb> startchan is missing. It should be a channum.

Ah. Missed that one -- also wasn't sure whether it was required.

After adding one, it definitely looks better:
Starting up as the master server.

Probed: /dev/video - S-Video

Using DVB card "VES1820 based DVB-C frontend"
tuning DVB-C to 394000000, srate=6900000

 bb> [lots of analog channels, I hope you didn't try to record from *them*]

No. They are for the analog card (cardid=1).

I use your grabber - thanks for writing that, by the way.


 bb> The channel_dvb table is missing, that's the most interesting one here.

Sorry, forgot. Provided below for reference.


It appears that I cannot switch to the DVB card for live TV. Whenever
hitting "C" in live TV mode, the screen goes black for a short moment
and then goes back to analog.

The error message I get in the log is:

ioctl VIDIOC_G_FMT: Invalid argument
strange error flushing buffer ... 


I know DVB support is still in a relatively early phase. Is this a
known issue? I seem to recall some discussions about switching live TV
between analog/DVB.

If anyone needs more data or has an idea for a fix, please let me
know. 

Regards,
Georg
