I just installed a 6981 in my mediaportal TVserver, in order to give me DVB-S2 support. I have an existing Pinnacle 7010 and blackgold 3450 in the same box doing dvb-s. The existing cards are working fine. I installed the 2.0.18 tbs drivers, running under win7 64bit, the 6981 card is seen fine, by mediaportal, and by DVBviewer. mobo is asus m2n-sli-deluxe (AMD athlon X2) if that makes any difference.
when I try to scan for channels with the 6981, I do not get any. Not a single one. I get a strong "signal", i.e. the signal bar at the bottom of the dvbviewer scan window shows a high value, but I get 0 channels/ programs found. similar behaviour in mediaportal.
in case it was a power issue I have connected the 6 pin power on the 6981 to a spare output on my PSU, that made no difference.
I've tried backtracking the 6981 drivers to a previous, no change to what I see.
I have no DISEQ or anything like that (dvbviewer channel scan seems to always ask for that, so I am selecting none?). My dish is at astra28.2D (usual for UK), I have a quattro LNB and a 16-way multiswitch between the LNB and the receivers.This is all working fine with all other sat receivers that I have on the end of the same cables, with absolutely no configuration fiddling needed other than telling it to scan astra 28.2d. the cables to the tbs6981 are cables that were previously into the BG3450 and were working absolutely fine when in there....
there must be some basic thing more that I need to do with this card, but I can't think what it must be.
cheers
