upnp implementation (been a mythtv user for over 6 years).  I've found that
some folders like "By Date" cause clients to just hang.  Using 'All
recordings' I do see a date ordered list, but selecting a HD BBC recoding
often results in a Error in the client player (iMediaShare/Dice Player on
Android for example).  Basically I have a poor user experience, kind of
given up using it.

master also runs twonky which serves a directory containing recordings from
the slave.  I sync the slave recording folder, as this allows the master to
serve content to other devices (laptops, android tablets, phones, other
ubuntu computers) with out having to have the slave (with all the tuner
h/w) & recordings powered on and running.  The 'low powered' master has
recordings symbolically linked from a directory so that twonky can serve up
content with a 'nice' name for each recording such as '20121224180800
Carols from King's.mpg'.

The oppo can work with either CIFS or upnp.  But given my difficulties with
mythtv's upnp, I use twonky.  The only problem I have with twonky serving
recordings is that there's no meta data in the recording mpg hence my
original question.   Might be on a hiding to nothing, but I am interested
in the oppo as it has excellent playback capabilities and is very low
powered.  It can also be used as a media renderer so - like mythfrontend -
you can 'throw' content at it from Android.  But it also allows you to
throw and render 'images' which is something that mythfrontend cannot
currently do.

can't you continue to use symlinks which effectively puts the metadata in
the filename and then use twonky as you have been?

You could set up a script to do as you suggest. Run it manually on your
existing recordings and then trigger it on recording completion for new
ones.
