I have had the HR-21/200 HD-DVR for over a year installed as my main DVR. It has worked consistently over the year. I recently got DirecTVtoPC working with help from the board. I am succussfully streaming my videos and pictures through my LAN to the box using TVersity. I plan on upgrading my basement system to a HD DVR for MVR in the future once pricing structure and upgrade path is released. I also am waiting shipment on an external eSATA to increase disk space. However, I am concerned that I do not see this particular model DVR mentioned too often. Are there any known issues I should be concerned with? Did DirecTV not manufacture alot of these models and why? Once I upgrade for MVR should I move this to the basement and make the newer model my main DVR? Thanks for any help you may have.
