lsdvb on mercury is only marginally better with the PCI zero's, but the other numbers swapped:

I was aware of that tool but didn't know it lists USB devices too.
Someone should fix it working properly for USB devices.
- 'scandvb' segfault at the end on its own.
I didn't see that.
- "scandvb /usr/share/dvb/dvb-t/uk-SandyHeath" (supposedly where I am) got a few "WARNING: >>> tuning failed!!!" and no list.
- 'w_scan -G -c GB'
have a few curious
WARNING: received garbage data: crc = 0xcc93876c; expected crc = 0xb81bb6c4
return a list of 26, with entries like (which seems to be vaguely correct):
BBC ONE;(null):522000:B8C23D0G32M64T8Y0:T:27500:101=2:102,106=eng:0:0:4173:9018:4173:0:100
Both scandvb and w_scan works here, same device used. I suspect your
signal is just simply too weak for reception. Small antenna coming with
those DVB sticks is not suitable unless you are living very near
transmitter. Try to connect it roof antenna. One thing that helps a lot
is to attach small bundled antenna to outside window.
There is both dvbscan and scandvb in Fedora dvb-apps. It is not clear
for me why two similar looking tools. Anyhow it is just scandvb which I
found working one.
So I just put it in ~/.mplayer:channels.conf
Took me a while to figure out that mplayer wants:
mplayer 'dvb://BBC ONE;(null)'
rather than anything else - curious about the ';(null)' part.
--------
Playing dvb://BBC ONE;(null).
dvb_tune Freq: 522000
ERROR IN SETTING DMX_FILTER 9018 for fd 4: ERRNO: 22ERROR, COULDN'T SET CHANNEL 8: Failed to open dvb://BBC ONE;(null).
----------
Typical channels.conf entry looks like that:
MTV3:714000000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_2_3:FEC_AUTO:QAM_64:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_8:HIERARCHY_NONE:305:561:49
And tuning to that channel using mplayer:
mplayer dvb://MTV3
However, I prefer VLC. Just open channels.conf to VLC and should show
playlist. Totem does not work anymore. at least stream used here in
Finland. It went broken when they changed from playbin to playbin2 which
is really shame as it is default video player for Gnome desktop.
At this point I am lost :-).
Not big surprise unfortunately :/
Unfortunately desktop integration is currently poor and most users are
coming from the HTPC.
