uhm eh hmm wtf ...
what exactly is this patch set doing and why?
ok on can store a whole subtitle file in one chunk, this isnt really sane
but hey the windoz kiddies arent sane.
still i dont see why that would require this mess

1. avi demuxer returns 1 chunk
2. ass parser splits chunk
3. add decoder makes many AVSubtitles ot of it
4. render renders out of the hundreads of AVSubtitles which are needed
   at the current frame

your patch does something else and iam not sure why ...

Breaking DRM is a little like attempting to break through a door even
though the window is wide open and the only thing in the house is a bunch
of things you dont want and which you would get tomorrow for free anyway
