You can transcode the HD content to a lower resolution. This has the obvious
drawback that you'll lose the HD-ness of the original. If you want to have
both, AFAIK the only solution is to go outside of MythTV to transcode the
recording to a lower resolution in the videos directory while keeping the
original. There are various ways to do this, mostly involving ffmpeg or
mencoder. You may be able to use one of the "user job" post-processing
options to run a script to do this from the MythTV interface, but I've never
looked into this option in any detail.
