Commented out the line in v4l-dvb-e0deca5f15a1. Tuned to channel with
czap

# czap "RTL 5"
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'

Tried to catch a stream with:

dvbstream 1910 1911 -o >RTL5.mpeg

dvbstream v0.5 - (C) Dave Chapman 2001-2004
Released under the GPL.
Latest version available from http://www.linuxstb.org/
Setting filter for PID 1910
Setting filter for PID 1911
Output to stdout
Streaming 2 streams
Caught signal 2 - closing cleanly.

File is non-empty this time, but mplayer still says it has no audio and
no video:

Playing RTL5.mpeg.
TS file format detected.
DEMUX OPEN, AUDIO_ID: -1, VIDEO_ID: -1, SUBTITLE_ID: -1,
PROBING UP TO 2000000, PROG: 0
NO VIDEO! NO AUDIO!  NO SUBS (yet)!
Opened TS demuxer, audio: ffffffff(pid -1), video: ffffffff(pid
-1)...POS=0
No stream found.
Exiting... (End of file)

Sure, here it is (only pasted the dvb-c card):

01:07.0 0480: 1131:7146 (rev 01)
        Subsystem: 1894:0020
        Flags: bus master, medium devsel, latency 32, IRQ 21
