I think you should be able to transcode directly to the name that you want
using the data from the database.

I'm not a programmer either, but I dabble.  Is this bash?  - I think that
the post in this thread by Ron Frazier may be the help you need here. Ron's
post is pasted (out of context) below)

Sound like Chris has a more permanent solution for you to explore (now or
maybe later) with mythrokuplayer, but if that does not work for your, why
not consider transcoding in place to the m4v file and then use mythlink to
generate the links for the roku box to read?

If this sounds like something you may want to explore then take a look at:
http://www.mythtv.org/wiki/Transcode_wrapper_stub

This is a python script that pretty much has all you need to do to
transcode in-place setup in it.  You just need to edit the transcode
command, and maybe a few others noted with comments.  Once that is in place
you can call it automatically as a userjob.  One note though, any
commercial flagging will probably need to be done after running the
userjob.

I only see a couple of potential reason not to do this. 1) the quality you
are transcoding to is not acceptable for your mythfrontend playback. and 2)
you want to permanant store the video and delete it from the recordings.

If #2 is your reason, then look at:
http://www.mythtv.org/wiki/Mythvidexport.py
and at: http://www.mythtv.org/wiki/Lossless_Cut

These are intended to export the recording to the video library with real
human readable names.
