Hi Thomas,
Ignore the SNR value. It is forced to 0000 even if the SNR is good
(enough). This is a missing feature in the DiBx000-drivers (x < 8).
Beside that, everything looks fine: locks are there, signal is
mid-range (~60 dBm I would estimate). ber = 0 and unc = 0, that means
no problem on the demodulator side.
How did you get the channels.conf? How do you know the video and audio
PID is correct?
Did you try to run scan or w_scan?
I used w_scan to get the the channels.conf file. I dont have the
transponder data, so 'scan' is of no use. Unless I extract them from the
output of w_scan, in which case the to generated files are identical on
the numbers.

This 'test.mpg' output file, however, shows no video at all, despite
it actually containing data. VLC reports 'nothing to play'.
What's the size of this file? (Should be ~1MB per second max on a very
good MPEG2-stream) Maybe you're receiving H264... then it can be more
and some versions of mplayer and vlc may not play it, because they are
not able to detect that it is H264 + AAC without stream-meta-data
(PAT, PMT).
The file varies in size, from around 3MB to around 7MB for the 5 seconds.
I have no idea if the PIDs are the correct ones, but at least they match
the output from dvbsnoop:
dvbsnoop -s pidscan
