Originally i was against this, with respect to incompatibility with almost
all existing decoders. Meanwhile i changed my mind completely, i think its a
good thing to do in any case.

The feature would not only allow to respect the specific properties of TVs,
but maybe also to correct AR errors that are recognised after the encoding
is finished ( only in 'extended' mode i guess ). If its easy to do and both
dshow filters for XviD, means ffdshow and xvid filter, support it, there are
no incompatibilities either, maybe only with elder playback filters.

As Christoph was saying, XviD was the first to support this feature of MPEG4
specs ;-) !
