[mythtvnz] Broken DVB-S setup

[Nick & Ann Read]

OK did some more testing. If I 'Watch TV' on the Satellite input, if 
shows 71% signal strength with SBS (Vertical?) and 53% with Freeview 
channels (Horizontal I think). But S/N of 4.5 dB in all cases. BE was 
originally zero, but after playing with LNB settings to try and wake 
something up, I am now getting BE of 3k-40k reported (after restoring 
the LNB settings). If I remove the cable from the LNB to the DVB card, 
signal strength drops to 0% but S/N stays at 4.4dB.

So, anyone want to guess if its the card or the LNB that's broken? I'm 
tempted to get a new DVB-S2 card cause that's easiest, but its $100 that 
I don't want to spend if the problem is the LNB...
