Ok. To be clear, I still can't get STV HD in EPG position 103, but I can now get the HD channel swap to work, whilst leaving STV SD in position 103. Not perfect, but a lot better than having nothing in position 103. Remember, this only applies to 'All Channels' bouquet, as this is the only bouquet that the HD channels swap works on.
I'm assuming you can browse files on your sat box, and copy these to and from your PC. If not, you'll need to do a bit of research into using FileZilla (or similar FTP program).
You need to edit the file skyuk.xml (I use Notepad++ on my PC to do this) which is located at /usr/lib/enigma2/python/Plugins/SystemPlugins/AutoBouquetsMaker/providers
and remove the following line:
Code:
<channel number="178" with="103" />
Simple as that!
