[mythtv-users] Meta-data for recordings

[Fred Watt]

Hi - does anyone know of a script or simple way of adding meta data tags 
to a recording .mpg file?  I wanted to populate tags as such as title 
etc, but was wondering if there was a way to inject the values rather 
than copy as in this example?

ffmpeg -i file.avi -vcodec copy -acodec copy -metadata title="Dancing 
Bear" -metadata comment="Title Created Using FFmpeg metadata tag" 
outputfile.avi

Is there a better way to do this using mythtv?

My use case is that I would like to expose recordings to a oppo 103 (via 
twonky upnp, or cifs) and use this as a play back device.
