I was specifically talking about the A&E samples above and I am not saying that it is only noticeable on bigger displays, what I am saying is that it will be "more noticeable" and potentionally "more objectionable" if you are looking with a larger display, especially if viewing distance remains constant.
And I still stand by original questions...
Will the average consumer notice? If noticed, will the average consumer find it objectionable? Keeping in mind the following things.
1.) The average consumer isn't going to measure bitrates (the only thing close to an objective measure) especially among different providers.
2.) The average consumer will have no good way to compare services in a controlled enviornment.
3.) The point of reference for the average consumer is going to be DVD or some other kind of NTSC video.
And ever since I have been in interested in home theatre, I have never considered cable or satellite suitable for critical viewing. Back in the days of analog cable and DirecTV, when I wanted to really watch a movie I viewed it on LaserDisc or a well mastered DVD which blew both cable and satellite out of the water. In the high-def world, a well mastered Blu-Ray destroys Cable, Over the Air, and Satellite.
