Comment (by saito1234):

 So, that means that after reencoding this (TEST) file, you got the same
 .ass back?

 That's interesting, I've tested it multiple times, and after encoding with
 the same command line, dumping the .ass from test.mkv, I got a '''124k'''
 file, (instead of '''242k'''), and these are the last lines in it:

 {{{

 }}}


 I have the following version installed:

 (Ubuntu 10.04)
 Also, as I've said, I think the .ass files are only cutted off before
 they're finished (with Error while decoding stream #0:2), when there's a
 lot of text formatting characters in the .ass file, could the problem be
 in something other than ffmpeg? (Sorry, but I'm relatively a beginner at
 Linux)
