The TV-card works in WinTV2000 but not in Mediaportal. I checked error.log and I saw this as well:

2007-11-13 01:30:30.328125 [ERROR][6]: SinkGraph:FAILED to connect Encoder->mpeg2 demuxer:80040217

Changed CaptureCardDefinitions into this:

<capturecard commercialname="Hauppauge PVR USB2 AVS Video Capture" capturename="Hauppauge PVR USB2 AVS Video Capture" devid="vid_2040&amp;pid_2400">
<capabilities tv="true" radio="true" mpeg2="true" mce="true" sw="false" bda="false"></capabilities>
<tv>

</tv>
</capturecard>

What's wrong here and why does it work within WinTV2000?
And it does find my channels with autoscan, without previews...

Problem solved, using this card definition:

<capturecard commercialname="Hauppauge PVR USB2 AVS" capturename="Hauppauge PVR USB2 AVS Video Capture" devid="vid_2040&amp;pid_2400">
<capabilities tv="true" radio="true" mpeg2="true" mce="false" sw="false" bda="false"/>
