The small TV set in the kitchen might be CRT while the big one in the 
living room is LCD (or any similar flat screen), and for the later 
double-buffering (or more) is employed as standard. These new screens 
are "slow" and create tons of artefact with standard definition TV or 
just the wrong rate.

Doing low-delay uncompressed transmission across countries, continents 
or between them is all at vain, when the flat-screen comes into the 
loop. It is often impossible to disable it.
