Technisat SS2, DISHnet 36" dish, unable to scan transponders...

Hi all. Forgive a newbie for asking a silly question:

I just got a SS2 DVB-S card today, installed it and ran a cable from the DishNet 36" oval dish on the roof. In anycase, trying to scan transponders on echostar 5,3 or DTV 1R, only showing 20% signal and 0 q on AltDvb. I import a transponder list from joshyfun and scan them, but get 0 results... So I'm obviously screwing up somewhere,where do I start?

Thanks

dish was used b4. I'm heading up to hooh my cable directly to the LNB (right now its hooked to their switch).
Funny thing though. Program called FAST SATFINDER showed 85-90% signal strength and the following:
@ 110w, 12224, r, 20000, lnb Ku CIR

Thanks

Figured it out. Had LNB settings all messed up. Using DishPro twin LNB should have had LOF set to 11250. Scanning and watching "green" chans in MyTheater. Thanks again.
