I just came across this thread and my issue also appeared suddenly. My issue is most notable when accessing the channel guide. At times, it can take 5-7 seconds before the channel guide will appear. Cycling through the program listings also gets slow.
I called DISH tech support and explained that the following steps were taken:
- I tried different remotes and experienced the same issue
- installed fresh batteries
- powered off and disconnected the AC for 10 minutes
As others have noted - a reset of the DVR remedies the problem "for a short time". The slowness visibly manifests itself as the day wears on.
DISH even sent a new remote but that has not helped.
ONE THING I DID NOTE - about 2 and a half weeks ago (this would put the time frame in mid-December 2011), there are times when the speed returns for now apparent reason. Then the slowness will come back again at various times. There is nothing happening such as power tools running, etc. that could contribute any sort of interference.
I also thought that perhaps the drive was too full. The message indicated that I had 38 hours of HD programming available. I deleted a number of shows and got to 48 hours of HD programming but there was no difference. However, the fact that the speed slows down and then speeds up at odd times would seem to negate drive capacity as the cause.
I suspect that there are some updates that are mucking up the performance but tech support sort of brushed my comments aside when I mentioned this.
