	Guys, this is, as far as I know, not a problem with Post houses but
the Broadcasters.
	We noticed a long time ago that it was possible to have this error
when encoding.
	I don't want to mention any brand names but, any of you have this
issue with HD encoding.

Thanks to Sean McKee and Digital Vision AB for supporting the TIG.

Have any of you noticed that lip sync errors seem to be inconsistent; one
minute they're off by 5-10 frames and then things "drift" back to normal and
then out again at odd times, not always coincident with feed switching or
other circumstances.  could this be a side effect of stat muxing?
