I'm curious about mythtv. I've got a tivo and I really enjoy it but I'm also considering a mythtv setup. What's your setup like? Could you install dual tuners like two hauppage hvr-1600 cards to record two shows at the same time? Is there a program guide like on the tivo or is it more like a vcr (manual recording). I'm not really looking to replace my tivo as it's damn simple for the family to use. I'm just thinking more as an addition to my current setup.
