ReplayTV RTV5516 160-Hour Digital Video Recorder
Got a Defective Unit
The 5504 unit I purchased has a defective infrared sensor, such that you can only operate the Replay by holding the remote three feet or closer to the unit.  Set up was quick and easy, and the Replay properly detected and obtained an IP address from my computer network router.  The download of the software and guide data took only about 10 minutes on my broadband internet connection. A pleasant surprise was a message after set-up that I had ten days before I was required to subscribe to the Replay TV subscription service. <br /> The controls and menus are intuitive and it certainly is easy to use.  However, quality control may be questionable given my experience, so you might have to go to the time and trouble to exchange your Replay.   I'm trying to decide whether I should exchange the 5504 or pay a little extra for a Tivo.
