------------------
I believe MPEG is in effect the true non proprietary standard having been
defined by the Motion Picture industry.  Although QT is proprietary, it
integrates very well with MPEG, I did experience the same problems with
versions of the MacOS below 8.1, never mind some legacy but much used
versions of Windows.
