Because if the video soruce sends HD, then the SD TV will not have picture.
For example, if output A goes to HDTV, and output B goes to SDTV, then, if you have your blu-ray ONLY goes to output A, then your HDTV @ output A will get HD signal. "
Substituting Output A = 1080p and Output B = 720p... is it true that if A and B are both live, then both will get 720p... but if only A is live, then A will get 1080p?
That is true. And, sometimes TVs that are in standby mode (the usual "off" mode) will still be active on their HDMI ports. If you think about it, this isn't too different than sending 1080p over component video - the 720p TV would still not understand that signal either. But, HDMI is needlessly complicated for situations like this.
Anyway, I can reduce the cost of your desired system a bit but not much. Take your present system and remove the DVD player. Take the cable TV box and put it on the component video outputs you are presently using for the DVD player.
You'll then need two HDMI distribution amps (< $100 unless you want 3D) and connect the apple TV and the new Blu-Ray player each to an HDMI distribution amp. The HDMI distribution outputs then go to the TV and projector as separate HDMI inputs to both. You'll also need a component video distribution amp (again fairly cheap) for the cable TV. You can eliminate one distribution amp if you go with the OPPO BDP-93.
Audio is as you have it today except add the 7.1-channel audio outputs from the Blu-Ray player.
That's all you need. If you go with the OPPO you can select 720p on one HDMI output and 1080p on the other HDMI output. That solves your HDMI problem. The AppleTV may have to live at 720p for both the TV and the projector to work with that input. Component video takes care of the cable TV and you won't lose any resolution there.
And, even if you get a new receiver you still have to figure out the 720p / 1080p dillemma with the receiver. The OPPO will really simplify your life in this case and keep you from needing a new receiver. However, depending upon how much you were planning to spend on a new receiver, the OPPO may be higher priced.
Short of that, I think your 720p TV is really your bottleneck to being able to solve this problem. While I know it only displays 720p, are you sure it can't handle a 1080i or 1080p input? Most 720p sets could handle 1080i inputs.
