I think what you want to do is:

	- Record stuff in HD from HD-3000

	- Do something with UserJobs to:
	
		- Call mythtranscode (or whatever program you want to
		  use) to create a low-res version of the program.

		- Copy the appropriate rows of the "recorded" table to
		  generate a new row for the low-res version (you'll
		  probably have to come up with a new title and/or
		  subtitle, like add "low-res" or something).

Now you will have both HD and low-res versions of the same program,
browseable/manipulable from all front-ends (of course the frontends
won't be able to view the HD versions). The obvious cost to all this
is increased storage space for both the high- and low-res versions of
programs. But everything remains nicely integrated into the MythTV UI,
and your SD frontend can delete both the high- and low-res versions of
a program when you've finished watching something.

Symlinks would be a completely independent issue, if you want to do
something about that for storage management.

The MythTV documentation has information on the variables available to
you for programming your user jobs.
