hello. I am trying to set up my tbs6922 with nextpvr. I have echo7 on diseq bb and echo 10 on diseq aa. I get no signal from either. it scans perfectly well with dvbdream but not with nextpvr or mediaportal. What am i missing and tbs please help. it says in your product info that my card would work with nextpvr and mediaportal and it is not working with either.
