Ya know, once upon a time, "Broadcast quality" used to mean
something.

Now it appears to mean, "How much advertising revenue can we
cram into something?"

Nobody gives a **** about "doing it right" all the way down the
line from the CEO to the techs.

I think to some extent, that depends on the 'quality' of the broadcaster
involved. I watch a lot of HD transmissions on sat, and most are superb.
I've never seen a sound / vision sync problem that I can remember. However,
I also watch some of the cheapo channels, and the whole production quality
can, as you say, be very variable. On these channels, I have often seen the
sync problem, so I guess that somewhere along the line, it's caused by cheap
production techniques, or maybe something to do with the bandwidth (cost) of
the data link from the programme producer to the uplink station, or maybe
the quality (cost) of the transponder that they are renting on the sat ?
