John, or anyone who is having the same problem, any chance of using
MythArchive to create a native archive of a file that doesn't work for
you and provide it for download somewhere?  Just let MythArchive create
a directory for the backup and zip up that directory. A native archive
will allow me to import that recording, including the same cut points
etc, so I can hopefully reproduce exactly what you are seeing. It's
something I simply cannot reproduce here using pal recordings.
