More info:

The LNB is set to universal (LNB LOF Low 9750, High, 10600, Switch 11700)

I have removed myth completely and downloaded and compiled the latest SVN,
which made no difference.

Interestingly I can't find the channels on any of the transponders listed as
Astra 2D  28.2E but can on 2A/B using scandvb or mythtv but i can lock
directly onto channels using dvbstream.

I had a look at the LNB settings on my sky digibox and they are set to 9.57,
10.6 and 22kHz tone=ON. I don't find anywhere in mythtv to set this 22kHz
tone but if i switch it off on my digibox, i loose a lot of channels. So i
have a feeling the myth isn't setting the LNB up properly, but given that I
knew ZERO about LNBs a week ago, I'm prepared to be proven wrong..

Any help, tips, pointers links would be be greatly appreciated.

TIA
