I was looking at the online user guide for the 722k and found this:
Changing UHF/IR Using the Switch
Your TV2 remote control has a switch to change from sending both IR and UHF signals to sending only IR. The switch comes preset to the UHF position, which sends both types of signals, but if you have a clear line of sight to the satellite receiver you’re controlling with this remote, then you can change the setting to the IR position to lessen the likelihood ofanother UHF remote interfering with yours. This is applicable for TV2 in Dual User mode.
Does this mean that you can control tuner 2 via IR? If so then it would be worth getting this unit just so I can move my Slingbox over to tuner 2. Assuming of course Sling has the codes to do this. Right now I have my slingbox on tuner of my VIP622 because it cannot control tuner 2 via IR signals.
