An annoying trend(s) noticed in 5.1 TV brodcasts

well since having my tv hooked up to my 7.1 system i have noticed three sound problems that are unacceptable, one many stations broadcast movies in what "appears" to be "5.1" one problem i have noticed that seems to be the most common in some networks is the left and right channels are blended directly into the left and right surrounds, another issue is many channels seem to have 3 center channels, by this i mean the dialogue is coming out of both the center and right and lefts, or in some very strange cases, ive seen the l/r "reverb" into the surrounds. another rare occasion is where there is no l/r but the l/r coming through the surrounds instead. i have yet to truly hear real 5.1 coming from an HD broadcast, anyone noticed this madness?
i've also noticed this is basically the same trick used in sports broadcasts that are supposed to be in "5.1", watched nascar the other day and it might as well been run through my Pro Logic IIx decoder, i got better imaging that way. the car noises were "reverbing" through the surrounds. my question is why would broadcast stations try to "fool" us into thinking we are getting real 5.1 rather then actually delivering?

Making broadcast surround sound is very difficult. Movies give engineer lots of time to do the job. Broadcast is instant, but it's still an improvement over stereo. You are kind of new around these parts and some Floyd Toole reading would be a very good thing for you.

Give those articles a good read and you will be on your way to understanding multi-channel much better.

Also discussion on TV go in the TV section.

yes but imo if they cant do it right, might as well downmix it to a Pro Logic II matrix and thanks for the links

If you sit in the sweet spot that's fine, but try sitting outside of it and you'll understand the issue with that.

when using pro logi II theres a sweet spot???, isnt there a sweet spot in all surround? ive been using PLIIx for anything stereo and didnt notice much of a difference except the imaging was not as accurate and that occasionaly the dialogue will "slip" out of the center for a few milliseconds

In a well matrixed system it's much larger than in a stereo system. If you read those papers you'll start to understand why. Toole is an excellent writer.
