[mythtv-users] How to force a transcode?

[Andy Burns]

I've got myth up an running nicely, with twin DVB-T tuners, I'm not 
transcoding to a lower quality immediately after recording, the 
commercial detection jobs run ok, I can view and edit the cutlist, and I 
can start the transcode jobto make the cuts take effect, so far so good.

Sometimes I decide I would like to hang onto a recording, so I cancel 
the auto-expire, I assume there is some way to force a transcode to a 
lower quality codec to save disk space, I've had a look in the wiki and 
mailing list archives but no joy, I get the feeling this is to to with 
RecordingGroups or PlaybackGroups but those concepts seem a little vague 
within the frontend, have I messad an obvious way to do this?

Thanks ...
