Notes regarding my dvb-c card on linux. At this point i already have my dvb-card usable, firmware loaded, so /dev/dvb/adapter0 was created.

• http://www.vdr-wiki.de/wiki/index.php/Hauptseite – vdr-wiki, also generic dvb@linux infos
• http://www.vdr-wiki.de/wiki/index.php/HDTV – vdr-wiki, hdtv

# a) get w_scan from http://wirbel.htpc-forum.de/w_scan/index2.html and compile it
# b) now lets create an initial-tuning-file, kaffeine can do a channel-scan with this

     w_scan -fc -c DE -x > initial-tuning-data.txt
     
# c) copy the file where kaffeine expects it
     cp initial-tuning-data.txt .kde/share/apps/kaffeine/dvb-c/mytown

# d) now we can scan for channels in kaffeine and watch.

apt-get install dvb-apps # or compile dvb-tools for yourself

# using the initial-tuning-data gathered with w_scan and the 'scan' utilits from dvb-apps
# we create the channels-ist:
scan initial-tuning-data.txt >channels.scan

# now czap can be used for channel-switching 
czap -c channels.scan -l                    # lists numbers of the channels
czap -c channels.scan -n 300                # tunes in channel #300

# if your mplayer is compiled with dvb-support you can use it:
# http://www.mplayerhq.hu/DOCS/HTML/en/mpeg_decoders.html
cp channels.scan ~/.mplayer/channels.conf
mplayer dvb://'Das Erste' -cache 4096

• kaffeine can hdtv natively, but makes trouble with my Terratec Cinergy 1200 DVB-C MK3, plain old tv works. Probably its because of the defaultish debian/xine codecs.

# now install x264 and mplayer (with x264 and dvb-support), instructions at mplayerhq.hu
# we already created the channels file:
ls -al ~/.mplayer/channels.conf

# i have three HD-channels available:
cat ~/.mplayer/channels.conf
Das Erste HD:338000000:INVERSION_AUTO:6900000:FEC_NONE:QAM_256:6010:6020:11100
ZDF HD:338000000:INVERSION_AUTO:6900000:FEC_NONE:QAM_256:6110:6120:11110
arte HD:338000000:INVERSION_AUTO:6900000:FEC_NONE:QAM_256:6210:6221:11120

# now to watch HDTV (thanks fefe for 'demuxer lavf' hinting!):
mplayer dvb://"arte HD" -demuxer lavf -cache 15000 -framedrop
