I had to change a few settings, namely the chip name (mine's the 713x and not the 7134) and one of the pins to get it recognized, but for the first time in MONTHS I was able to use my tv card with mediaportal!!!
I'm so happy! weeee!
The image freezes if I try to use timeshift or record tv, but its working for the first time! Thank you so much!
Now that I have tv working, i have another problem... no sound...
This card uses the line-in feature to get the sound into the soundcard. I was finally able to make a cable to connect that to the internal aux port and it works just fine in MSI's own program.
How do I tell MediaPortal to get the sound from there?
