I tried this while playing a 1080i MPEG2 program, and I didn’t see much of
a difference in memory usage.  Mythfrontend stays around 66% of my memory
usage.  A little high, but the system is stable.   I remembered I had
installed ‘mythplugins-light’ when I set this up, but don’t use any of
them.  So, I removed that package, and the memory usage dropped to ~50%,
which leaves a lot of head room.

While the memory didn’t go up with the Info menu displayed, the CPU went
from ~40% to ~175%.  Playback was still okay, that was just a little
surprising for a basic UI.
