Hi Neil,

Sorry, I can't help with the Compro, but maybe with the Technisat :)

The above is for the Compro and not the Skystar, but <access denied> is 
likely to just be that it needs root.

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.

This is how I ran it on mine quite recently whilst fixing a bug in the 
driver (you might need to change the adapter number on -a):
# dvbv5-scan -a 0 -l EXTENDED /usr/share/dvbv5/dvb-s/Astra-28.2E

That bug was patched only a few weeks ago so the above will probably 
fail on some of the transponders. MythTV wasn't affected though so that 
should scan fine, aslong as all the other things with myth are setup ok 
- it's quite fiddly!
