Hey Mike,
Probably not the place for this, but I keep forgetting to ask. Since I absolutely can not get Myth TV working right, what other program can I use to play the USB Hauppauge PVR card on? It is about as useful as a door stop at this point. Would sure be nice to be able to watch TV on it, since it is so much clearer than an internal card I am using.
