Note that this was assuming that WebSRT should be an extension of SRT. If  
that's not true, we can choose more freely.

; look mostly like typos, sometimes where " was intended.

# seems to have been mostly used as some kind of emphasis, with #  
sentences like this #

Note, that lots of the files are in languages and encodings unknown to me,  
so my guesses shouldn't be taken too seriously. It's obvious that if  
WebSRT is an extension of SRT (which I no longer think is a good idea),  
then *some* content will break.
