Why don't you want to use your HTS? You can always get a programmable remote like a Harmony (that's what I do) and control everything with a single remote. I guess I don't really understand your setup. I have everything running thru my avr with a single HDMI out to the tv and an optical out to the avr for OTA audio. The tv sound is turned off and all audio (OTA, blu-ray, AppleTV2) is played thru the avr. I don't know how well the audio would be playing it out of the headphone jack to powered speakers. The audio would probably only be stereo so you'd be missing a lot. Audio out (optical) to a soundbar would be the better of the two options I would think.
