I think that it might have something to do with the fact that the HR34 has 5 tuners, while the HR24 only has 2.
Say you have 1 TV remotely connected to the HR24, that means that if someone is watching TV you would no longer be able to record a show in the background.
With the HR34 all 3 RVU can be used, and you still have 2 tuners available for the box itself (1 person watching, and 1 more show recording in the background, or 2 shows recording in the background)
I could be wrong, been away from DTV for a year, coming back on Tuesday
