What you can do is limited only by the capabilities of the encoder you
use (e.g. ffmpeg). My script always produces h264 video in an mp4
container, but little tweaks to the script could change that to
anything else that ffmpeg supports. Changing from HD to SD is
just a case of specifying the frame size.

Here's one of the user jobs I've set up in MythTv to use the script,
in case you want to try it out.

/home/paul/bin/mythar --chanid "%CHANID%" --starttime "%STARTTIME%" 
--title "%TITLE%" --subtitle "%SUBTITLE%" --outdir 
/home/public/video/Archive --interlaced
