I use composite actually, in the screenshot you can see it has
Component/S-Video/Composite.

I currently use FlyDS with nVidia WDM Video Capture and it works well,
but I want to use Windows MCE 2005's Watch TV feature, that's why I
asked.

Do you have any idea how to get it to work? I'm sure it's possible
since the web site I linked to shows it is.
