If ther receiver does not have the same latency for both the audio and
video paths, that is a flaw in the receiver or reciever setup, and not a
flaw in the DTV spec.

There also exist encoder boxes that don't keep things in sync.  This is
the encoders fault then though, not DTV.

Then there are 1001 places where human error can cause sync problems.

The DTV spec may not be perfect, but it isn't to blame for sync
problems.
