[Pyparsing] Problem parsing block

[Robin Siebler]

I have grammar that works for almost all of my file now. However, there
is still one block I am having trouble with. There are 3 blocks that
are similar: audio track, video track and subtitle track. For some
reason, I can't get the correct grammar for the subtitle block. What am
I doing wrong?
