Some time ago I updated my HR20s to HR24s and at the time was very happy with the huge speed increase. Now a couple years later I am finding that our HR24s seem to have gotten sluggish just like the HR20s used to be. I know this must be a software issue, though I can't imagine why. I haven't been paying much attention to upgrades since the HR24 and I am wondering what the latest and greatest receiver is. I am not so interested in a whole home setup, just an HD DVR.
