in this case keep the muxrate to 20000 and no dts should underflow

I don't know the specification for HD content, maybe ATSC defines them.
In any case keeping the vbuf value as small as possible is recommended
for the sake of playability on the largest possible number of players.

Maybe you can find out the currently used vbuf in the TS with:
$ mpeg2desc -u < file.ts | grep pstd

(mpeg2desc is part of dvdauthor)
