Well, so much for buying a 922. I was looking forward to the new Sling-enabled receiver, but it seems that it would just complicate my setup for very little benefit.
Right now I can watch HD content on my 2nd TV using the component output from my 622. If both TV's are in use, I can switch to dual mode and watch something different in SD on my 2nd TV. All of this can currently be controlled by the same remote.
If I purchase a 922, I will need the main receiver plus another sling catcher box. I'm assuming I could still watch TV1 on my 2nd TV through the component output, but then if I need to switch to TV2 it will require using a completely separate remote. While that may work for me, I can tell you there is no way my girlfriend will ever figure out which remote she needs to use when.
This would have been a great box if it had sling capability on a 3rd tuner, but unfortunately it really doesn't interest me anymore.
