Was just told by a high level person @ DTV that the HR24-100 has been discontinued. The remaining versions will be the HR24-200 and the HR24-500. Now bear in mind that at any level at DTV that one can ask the same question 5 times and get 6 different answers so this may or may not be true. If it is true then DTV has discontinued the HR24-100 version which has proved to be reliable and works and plays well with remotes, AM21s, and external eSATA drives in favor of the HR24-500 which has proven to not work and play well with remotes (stuttering), AM21s, and external eSATA drives. So now instead of praying you get an HR24-100 you can pray you get a Wednesday HR24-500 and not a Monday or Friday one. Also hoping the DTV engineers can get these HR24-500 problems resolved with a software spool in the near future.
