Just registering more frustration with this issue. It continues here with an HR24-200 that replaced an HR25-500 with these same issues. I've mentioned this in some other places, but going to put it here too, because I feel like there must be something to it... This all started with 66C, and go to the point where it was actually impacting my entire networks performance - my download speeds were cut in half for a few weeks. Must have just been some crazy collisions going on. I have whole home DVR and the connection kit. Curiously two other boxes do not seem impacted, just one. I feel like it has to be with the network stack somewhere, but I just can't isolate it. The 66bd update has returned the rest of my network to normal, but the DVR is just as bad, if not worse.
