I installed the latest CVS on my system and now I cant get my tv to work. The picture is totaly black. When I press the tv on button it never gets activated. I have a Hauppauge pvr150 tunercard and analog cable tv. If I do an autotune the card finds alot of channels (alot more then I can get actually). Does anyone have any tips & trix I can try? I made a backup of mediaportal so I can go back to my previous cvs but the music section is working so much better in this new build so I'll try just about anything first.
