DTV question..

Just upgraded from an old analog tv to a Samsung DTV. The first
problem I noticed is the lip sync audio-to-video time delay on NBC's
national digital programs. While analog broadcast has some small time
delay, digital has 2x-3x more delay, making it almost impossible to
watch. Local station in-house digital programming does not have any
more delay than analog, but as soon as they switch to national
programming, the delay goes to hell. ABC & CBS does not have nearly
the delay that NBC has. I brought the problem to the attention of the
local NBC station, but they said & did nothing.
Does anyone else notice the problem, or is it generated by my local
station?
