Good :) I knew why I waited with the next mkvtoolnix release :)

Yeah yeah, I was lazy (no, I was ignorant). First I didn't know that the
SPU packets were inside a MPEG stream, and I just used the difference
between two entries in the .idx file as the duration.
How do I extract the duration from the SPU packets? I should probably
look at mplayer's sources, but maybe you have a quick explanation ;)

Ok, sounds reasonable. One entry corresponds to one line in the .idx
file, or should we just ignore those lines and parse the MPEG stream and
use those timestamps?

I have no idea :)
Great you're working on it :)
