Is there a way to use mythexport to achieve something similar where you
could have myth down-convert and save a duplicate version of the video file
in a seperate recording group and add it to the database as well. Just not
try to do it live. Basically create a user job that downconverts and adds
it back to the database so I can add that user job to the shows that I will
most likely want to watch on SD capable machine. Only downside is the
diskspace on your backend.
