The first of the two figures given for a transponder (10773000) is the
frequency, followed by the polarity (horizontal or vertical) followed by the
symbol rate (22000000) - I presume that you've had a go with these figures?

I found it easier (for a certain value of "easy") to do the channel scan
separately and then import it:
~# scan /usr/share/doc/dvb-utils/examples/scan/dvb-s/Astra-28.2E | tee
/home/mythtv/channels.conf

This pulls in every channel listed by the satellite, and the import process
drops out the ones that are encrypted (assuming you select that option) - it
still leaves a whole bunch of stuff most of which you probably won't want,
and which don't match up against anything in the Radio Times xmltv feed
(there must be a better way to match these together, but I haven't found it
yet...!)

I'm in the process of trying a fresh Knoppmyth R5F27 install on a separate
hard disk to my main working setup (which doesn't have all the channels I
want, and I don't want to break anything by messing around!) - I'm trying to
document everything necessary to get up and running with a Nova-S Plus card
to receive all the Freesat stuff that's possible, as the existing
documentation is a bit lacking for UK folk.

Not sure if this helps - or if anyone else is going (or has gone) through a
similar process and can offer additional guidance and support...
