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?
