I have just purchased this card but have now found it doesnt work out of the box with Media Portal which is my choice for a Media Center.

Can someone please urgently help me if there is a work around. I searched the forums and found a way to add it in to the capurecarddefinions.xml file but I either didnt do it correctly or it doesnt work for me.

I want to use the Analog tuner of the DVT1800
