You could always do manual transcoding.  If you specify an appropriate 
multi-pass transcode with variable bitrate using a bitrate chosen 
appropriately for the output resolution and CODEC, you can get good 
quality (how to manually transcode is left as an exercise to the reader 
;).  However, if your container is anything other than Myth's NUV 
container or MPEG-2, you're probably better off putting the recording 
into MythVideo instead of trying to keep it in recordings.
