You also told us your HR24 was dying.
Which is how you got the Genie!
I did the speed test, and you are right about 3.5 seconds for HR34. But I also played with the HR24s and its about 2 seconds!
Sorry but the HR 24 is a much more responsive receiver across the board then the HR34.
HR24 and H25 are about a dead lock as far as speed.
Setup a speed poll?
Yes, my HR24-500 was failing but it's channel changing speed wasn't effected and remained the same throughout the years I had it. My HR34-700 is still faster than my HR24-500 was.
