AHP and IWatchout uses only the Va11 usb capture for video, you can use the receiver and run to a tv card but you would have to use a different software to view it. This is one of the items in our wish list, to use any capture device.
But to this date, it hasn't changed. If you are trying to view video in AHP and you don't have the Va11 plugged in, it will probably give you an errror. Hope this helps.
