Here the problems begin:
It has references AND Movie Data! What should be done ?
As the demuxer->video-buffer is already initialised and sued by the
reference-playlist it would be wise to use it that way, then line
450 should be changed from:
-if (flags==5) // reference & header sent
- return 1;
to:
+if ((flags==5) || (flags==7)) // reference & header sent
+ return 1;
or:
+if (flags&5==5) // reference & header sent
+ return 1;
But there remains one problem, that could occur if there was a big file with a
big DAT-Section ...
In lines 418-422:
if(flags==3){
// if we're over the headers, then we can stop parsing here!
demuxer->priv=priv;
return 1;
}
This should be done also, if a playlist was detected (flag|=4 set), but with
the difference that flag 4 set means:
free(priv); return 1;
However all solutions I could think of very much complicate the code and I
disliked them, so I wait for a helping hand from heaven or Arpi ;-)

PS: Sorry, for this Bug, I remember well that we talked about silly files
having REF- and -MDAT-section and then in the end I forgot about it :-(
