The iTVC16 which is used on the PVR-250 version 2 doesn't implement a decoder which is why the decoder firmware version isn't displayed.

The driver defaults to channel 4 which is mapped to 62.25 MHz by the BG channel map used by the driver. Is something broadcast on that frequency in your area and do you have a good antenna or cable connection attached to the coax connector on the card?

Enclosed is a little utility for changing channels and selecting the input.
