Comment (by jpoet):

 When trying to detect a "new" access unit (AU), one of the things to look
 for is a change in the nal_ref_idc value.

 nal_ref_idc is part of '''every''' NAL UNIT, and we are currently testing
 to see if it changed for '''every''' NAL UNIT.  Re-reading
 T-REC-H.264-200711-I!!PDF-E.pdf, I don't think that is correct.  When
 looking for a "new" AU, the nal_ref_idc should only be tested when the
 current NAL UNIT is a "slice".

 I have attached a patch which makes this change.  I have tested it with
 HD-PVR recordings, and it does not seem to cause anything bad to happen.

 It would be nice if someone else would read the spec to see if they
 interpret it the same way.
