 Info:
 -----
 
-All info packets with the same chapter_id and stream_id are repeated info
-packets and MUST be binary identical.
-
-All info packets MUST appear after main headers at begginning of file, and
-SHOULD be repeated after all main headers unless they are very large.
-
-Info frames can be used to describe the file or some part of it (chapters)
-
-Info SHOULD be stored in global packets instead of info streams/frames if
-possible, and the amount of data is not large.
+If a info packet is stored anywhere then a muxer MUST also store an identical
+info packet after every main-stream-header set
 
-If 2 info frames have the same chapter_id and stream_id then the earlier
-MUST be ignored (the last info frame is the most correct, this allows
-updating or correcting info)
+If a demuxer has seen several info packets with the same chapter_id and
+stream_id then it MUST ignore all but the one with the highest position in
+the file
 
-Info frames MUST be keyframes
+demxuxers SHOULD not search the whole file for info packets
