I did do this long ago, but don’t remember whether they are defined in the frontend or backend.</div><br><div><br></div></div></div></blockquote><br></div><div>Additional note: they are defined in mythtv-setup under "3. Recording Profiles”.

From what I can see the built in transcode options don't work at all and you have to build a UserJob to do any transcoding.
