The top-of-the-line ViP622 is a major advance in DVRs, not only recording HD with superb picture quality, but also offering dual tuners (for watching one show and recording another, watching two different shows on two TVs, or recording two shows simultaneously), copious hard-drive space (200 hours of standard definition; 30 hours of high definition), support for Dolby Digital 5.1 audio, and the ability to send a signal to a second TV (in SD only) without running cables between the DVR and the second TV.
