Had to have my HR-24/100 replaced due to the fan quitting. They sent me a new HR-24/500 receiver. I know it shouldn't make a difference with the remote but I've had to reset the remote several times to set up RF mode. When I finally got it to work the remote is double entering numbers and when pushing up arrow it's skipping several lines in the guide. I know this may be nit picking but its also very aggravating. Any thoughts and or ideas would be appreciated. After 3 calls to tech support there's no help in site.
