You are in the userspace, root should not be needed: On Debian/Ubuntu you need to add your user to the group "video" ...

> A few problems here - that's dvbv5 format and not channel so best to just skip the input-format, also 11719500 doesn't exist on 28.2E anymore, you probably want to be running this as root, and you should be specifying the lnb type.

* Add the user to the group (video)
* logout, login,
* run dvbv5-scan as Jem mentioned (choose the right adapter with -a n)
the -l EXTENDED is required for Astra-28.E ... more help on LNBf
$ dvbv5-scan -l help
* does scan work? --> your card is working!
Next step: test streaming
* with channel file (dvb_channel.conf) run ... (set ADAPTER, FRONTEND and channel to your needs)
$ dvbv5-zap \
--adapter $ADAPTER --frontend $FRONTEND \
-v \
-r \
-l EXTENDED \
-c dvb_channel.conf \
"$channel"
as output, you should see lines like ...
Lock (0x1f) Signal= -31,52dBm C/N= 13,62dB postBER= 0
... does this work? ... OK, let it run / don't break it and ..
* open a new terminal session and type ...
$ mpv /dev/dvb/adapter${ADAPTER}/dvr0 --hwdec=auto
... mpv shows your TV channel, right? --> everything works fine.
this was a complete roundtrip ... I have no MythTV experience,
may you ask into a MythTV Forum.
