Theoretically subpicture subtitles could come from a separate file (we don't
support that yet, but there are .sub files in mpeg format with embedded
dvd-style subpics and a separate .idx file).

Well, I guess that's just tough luck. Not sure if there's a better way.
subparse and/or demuxers could be made to ignore duplicate seek events (I think
we should be able to tell duplicates from the event serial number).
