Hi, I installed Media Portal on a 'clean installation' (I made a ghost image of my PC before to begin install/remove Pinnacle MediaCenter ! ), and the installation process terminates without errors.
My Pinnacle 3010ix function quite well with the Pinnacle MediaCenter, but under TV-Server, doesn't found any channel (Analog/DVB).
Maybe the problem concerne the TVServer encoders, but...where may I found a supported audio encoder for my card?
Thank you for your attention
