i dunno, maybe some hardware decoders have problems with it
feel free to send a patch which uses CODEC_FLAG_LOW_DELAY to set 
low_delay

iam not exactly sure what you propose but i doubt it will result in a valid
mpeg-ps stream ...
anyway, IMHO mpeg-ps is unsuitable for low delay as its hard enough to
generate a valid stream if delay is unimportant but if you can gurantee
that the muxed stream is valid then iam not against applying a patch
which reduces the delay ...
