OK

Well, obviously you'll need to make sure it is using the right LNB (DiSEqC

I presume?) Can you get other freeview channels on Hpol?



Is the skew on your LNB correct? SBS is a lower signal level than freeview

and is more picky about the skew being exactly right. I've seen some cases

where freeview has worked but SBS has not, then gone and looked at the dish

and seen the skew is off. Adjusting this has always fixed the problem.



If all is correct maybe there is an issue with your card or LNB, what LNB

do you have for D1?



The card should be producing ~13V when tuning Vpol, if it is producing

~18V it is still scanning on Hpol.
