Thanks.  This build (using Normal profile) does use less CPU than the
64 bit build from source forge.

However, for this build, playback seems always to default to a forced
4:3 aspect ratio.  The only way I could figure around it was to force
16:9 aspect ratio in the playback settings.  Had you noticed this?
