Karl,
I have a functional PVR-500 that I am willing to give to you for the price of
postage. That will keep your wallet nearly closed. I just got the inevitable
letter from Time-Warner that they are shutting down analog TV in my neighborhood
next month. That caused me to stop running a slave backend that contained the card.
