	Hi, do you have interest in contributing to improve the PGS
subtitle support? Reimar did write this code (PGS), but it needs further
development. I'd appreciate since Reimar alone maybe is too busy and
can't finish the PGS patch soon. Thanks.

	Ps: what it needs to be finished is to support PGS using the
default demuxer (not lavf) and to make subtitles disappear in time. It
seems ffmpeg needs to be fixed.
