Might be too late for the original poster, but there is a device that has been out for a while that can do this, minus the HD part. It works for what it does, and is in-expensive. There's also no lag as stated before. That happens when you try to do this with a regular tuner or PVR, because they buffer the playback, which is what allows you to pause "live" TV. If you have a Tivo or similar device, watch an analog feed on another TV at the same time and you will see it's about 5 seconds or so behind. That is why. Anyways, the device is the Adaptec GameBridge AVC-1400. There is also a 1410 which is the game adapter plus it adds a tuner. It should be noted again that this does NOT have HD inputs. You are only going to get that out of a true tuner, and then you will have the lag. http://forums.xisto.com/no_longer_exists/
