snr showing zero on some channels

[logie110]

Hi Guys...got the gigablue 800 hd se and have managed to get cccam working with open aaf image..However i have strange problem in that when switching between certain channnels the snr drops to zero..channel list is 100 % up to date and i have some sd and hd channels working while other sd and hd channels drop to zero snr..

the terrstrial tuner is working 100 percent its just the dvbs tuner giving me problems.
Any ideas in what im missing?

cheers

I would first try latest Team Red image as the AAF image is still in beta stage.

If same issue check the usual, LNB, LNB skew, alginment, coax etc....
