I may have answered you incorrectly before and I'll try to straighten out some terminology before I answer again.I have the standard red, black, wire and ground wire going into the sub panel. The red and black are each hooked to the Hot and are different phased. All of the circuits are tied in to the sub-panel and are grounded commonly back to the main panel.(They are not grounded at the sub-panel, but are tied together and connected to the main. - which is code, and often not followed.)
If by Leg, you mean Phase (+ or -) - then both #9 and #10 are on the same phase. But, it makes no difference whether they are on the same phase or different phase - I just tried plugging in the TV on a different phase and the slight hum is still there.
Yes, I also put all of my audio and video components on the same phase to try to avoid problems like I am having.

Looks like you got the wiring right (as far as my knowledge goes). Are you connected to cable? Do you have a cable ground fault interuptor in place? That'd be my next guess (cable has a different ground and can cause a hum). That cured a small hum in my system.
If that desn't cure it any chance you could try a different TV in the same outlet? Or the same TV in another room with a different stereo system? Narrowing it down would be my next thought.
Finally after that, is all your wiring neatly organized? Wires piled on top another can cause hum issues as well.
But I also have this same antenna hooked to my tuner, and that never caused a hum. Also it is not a 'ground loop' hum which is much louder (I've had those before). This is much quieter and I could live with it.

There still has to be a ground (and it'd be not the same as your electrical). Try unplugging the antenna from both. If that removes the hum then buy the interuptor (Ratshack, etc).
This is NOT a ground loop hum, it is much quieter than that.I am guessing that it is caused by over the air interference rather than wiring itself, as my other TV did NOT cause this problem with the same identical wiring.
