The TiVo Series3 does an excellent job of recording HD and SD programming. I connected the device to a 50-inch Samsung plasma display via HDMI, which is a new port for TiVo (it also has component outputs). I set it to record two programs simultaneously, nonstop, over a couple days, and the device performed like a champ. TiVo says the unit will record up to 52 hours at its best-quality setting (thanks to the 250GB hard drive), but that's for standard-definition programs--you can record only 25 to 35 hours of HD programs..
