Your suggested solutions have never worked to fix any of the sync
situations I have encountered wherein I attempted such potential
corrective actions. Additionally, while the least expensive box in
the chain is the one I own, the greatest preponderance of "boxes" in
the chain are not mine, but belong to the broadcasters. Therefore,
the highest potential for such issues rests with them, not with the
end user.
That spoken like a tech noob. Any time computers get involved in a
process the potential for mayhem increases. With digital TV the
audio and
video streams remain separate throughout so inattention at any
point can
get them out of sync. Anyone in the chain, including you, can mess
it up.
Maybe your local station cut corners on their new equipment? Maybe you
should have bought a more expensive digital TV? It is hard to say.
The "tech noob," that being me as described by yourself, sez that
WETA essentially agrees with my assessment. Their return e-mail to
me acknowledges that digital transmission of signals in the
production and distribution of programs has made audio/video
synchronization problems worse than they ever were previously. WETA
hopes that as the transition to digital TV progresses, the problems
can be mostly eliminated.
They go on to say that problems on the reception end can also lead
to such difficulties. However, in my home, I have three digital TV
receivers, all of differing brands and types. I have, on numerous
occasions, verified these sync problems by tuning all three receivers
to the exact same channel, and in every instance when I have done
this form of test, all three receivers exhibited precisely the same
amount and type of out-of-sync symptoms. Therefore, I can say with a
very high degree of assuredness that the problem is almost certainly
not the equipment on my end. The "noob" has spoken. Back to you.
