[Pyparsing] Problem parsing block

[Robin S. <rob...@ds...>]

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?

Here is the relevant code:
