ryandh -
Thanks for identifying the location of the Tivo Remote Address as being on the Slingbox and not the player - I sure wish it had been the easy route of a quick change to a player file. Actually, the Svid/Audio cable switch box for the two Tivos' inputs to the Slingbox works the best for me as the two Tivos must be ON 24/7 to do their job so without that switch I would have to disconnect cables to achieve the "turned off box" result. Also, as it turns out, it appears to be easier and maybe faster to just go to the Tivos themselves and flip their Remote Addresses between them vs. rerunning the Slingbox Setup. So, the Slingbox would always be signaling to the Remote Address "1" but I would "flip" the Tivo boxes Remote Addresses and throw the switch and then out the door I go. Granted, it is all manual to select which Tivo I want to watch away from home via the Slingbox AV before leaving.

I may not fully understand your recommendation of having both the Tivos plugged into the Slingbox AV at the same time. As I understand it, one of the Tivos must be off or in Standby all the time to avoid "shorting the signals" so to say for the whole system - not just the Slingbox. Standby does not appear to be an option for us since the TV is our primary viewing and we "flip" between the two Tivos for watching recorded shows constantly (going into Standby adds more steps and being almost 70 we do not need more steps). For us, viewing through the Slingbox is just secondary for away from home.

Effectively, it now appears that the long-range solution to this is a second Slingbox (Classic, AV, or Solo) or a changeover to a Pro.
