Try the (default configuration of the) Slim playback profile.  Note that 
there's no shame in using Slim on a beefy machine (I do).

If you don't have the defaults (i.e. if you modified the examples rather 
than creating your own profile group), see 
http://www.mythtv.org/wiki/index.php/Playback_profiles  for how to reset 
them (specifically, 
http://www.mythtv.org/wiki/index.php/Playback_profiles#Default_profile_groups 
).
