I downloaded more than half of the file now, and you're definitely right.
I definitely think this is the correct behaviour though, since the 
file's CC data seems to actually contains no text at all (up to this 
point :-)).
I sneaked in some character/control chars count code and it actually 
seems that, even if all of the CC data contained there is EIA608 encoded 
(the standard for closed captions) it actually contains neither 
printable characters nor control codes. So, even if it is correctly 
formatted, it's basically empty.
To doublecheck my assumption, I played it back with xine (on which, as I 
said, my code is based) and it displays no CCs as well. So I guess there 
actually are no CCs to display...
As I said, I "guess" because I am not at all an expert in this field, I 
basically just know about closed captions what was in the xine CC decoder...


Cheers.
