For starters I LOVE THIS MACHINE!!!! lol I am very happy with my purchase. I love being able to record two shows at once, it is freakin' awesome. I do not yet have HD but I well be getting an HDTV soon and it will be more awesome!! I previously had an old series 2 that i bought back in '04. It only had 40 hours recording capacity on it. This thing is way better w/180hrs! Well off to play with my new TiVo, bye.
