I'm considering picking up Sony's HT-CT150 and appreciate your input before I do...
I'd like to do what I think you've described:
AppleTV and DVR via their respective HDMI cables to the HT-CT150 (to handle audio) then one HDMI cable from the HT-CT150 to my Sony HDTV carrying video. I may have to juggle DVR, HT-CT150 and TV remotes (plus my iPhone to manage AppleTV).
From your experience, this should work, yea?
Thank you for your time!
