Anomander,
I'll bet it is the age of the box, I have a HR22-100 if that helps.
I have the HR22-100 also. I'll mess around with it tomorrow when I am off from work. It's no big deal if I have to be on my network, but I do think that is pretty slick it gets the signal from the satellite. Which leads me to another point and slightly off topic.
It would be nice instead of buying packages of channels, if we could just only but certain TV shows, or a series of shows. With the Sim cards in the boxes you would think they should be able to tell the box which signal to unscramble.
