I agree, now is the time to make it right. Just some things :
- how big is the overhead introduced by the MPEG PS ?
- if we leave it like we have it now, will it be easier for other apps
or hardware devices to support this with the MPEG PS ?
- when demuxing it from the MKV, can we restore the original .sub file ?
