Had some success with this but now hit another wall I'm out of ideas  
on. I tweaked the dish sufficiently to get a lock on the SBS channels  
and was able to scan and add the channels to the two Input Connections  
I've got defined in Myth (two TechnoSat DVB-S cards). However, when I  
browse to any of these channels under live TV Myth can't get a lock  
(despite the signal strength and S/N readings being higher than what I  
get for Freeview channels.  I thought it might be the wrong polarity  
bug but the values in the dtv_multiplex table in mythconverg look OK  
(to me at least).

A test with dvbstream on the command line shows I can get a lock on  
streams from this frequency.

1 row in set (0.02 sec)

No recordings were taking place during the tests so there was no  
reason for Myth to lock the polarity to Horizontal but I suspect that  
this is what's happening. I would've thought I could just scan for  
these additional channels, add them to my existing Inputs and restart  
Myth back-end  and all would be well. Am I missing a step here?

Cheers,
