Hi, I have decided to pass to MediaPortal in how much I must manage two cards TV (and MCE obviously does not succeed to us).
The problem is following: after to have completely installed operating system, I install MP.
MP finds the 3 cards (Hauppage HVR-1300 has 2 tuner), finds the channels list, but when I go to try to see the TV the screen remains black and the following message appears: “Live TV in background No Video/TV playing Make sure a video is playing”
I thinks that the problem depends on the EVR…
If there is someone that has had my same problem and has resolved it…. Thanks and hello

Mistake:
TV Card is: HAUPPAUGE HVR-1300!!!! (no HAUPPAUGE HVR-3000!!)
