Does Comcast have a channel which can display multiple channels at one time (like a quad chart - one selected for audio)? If not when do they expect to provide this simple and popular feature?
Cox, Charter, and AT&T had this but I have not seen it with Comcast. I can't even PIP because the Comcast Box does not provide two outputs.

Thanks for the quick reply. I hope they consider it. I believe I can achieve this easy enough with over-air HDTV as an alternative to Comcast Cable.
My TV allows 2 x receiver inputs and has PiP that can take the UHF signal and TDM split up to 4 pictures. The cable box's problem is that it limits just the one channel information/data from the box to the TV at a time and does not allow to more than one Channel mux'ed over the line from the Box to the TV.
There is also a startup called 4SeTV that developed a mobile system version to do this too.
