At the expense of CPU and disk space.

But 480x480 or 544x480 aren't 4:3 either. MythTV scales
to fullscreen so assuming your TV or monitor is 4:3,
any recording resolution will look correct. For TV in a
window, there is a Setup->Playback checkbox to force
4:3 regardless of the recording resolution.
