They are files that have been through an 'mythffmpeg -i infile.ts
-map... -copy... outfile.ts' process, and when presented as a recording
the --rebuild process works. I just wanted to try different options
without having to regenerate all the initial file attributes before
trying again.. and again... and again... So I think it's the link from
videomarkup? to the OSD that seems to be missing.
