I should have said that my MythTV box with the GT 710 has a 2.6 GHz 
core2duo running 64-bit F27.  Panning h264 HD content used to show a 
slightly non-rigid picture,  That didn't happen with display via DLNA, 
where the TV does the rendering.  I haven't noticed this effect 
recently, running a later nVidia driver and with ffmpeg-related and 
other changes in MythTV, but maybe I haven't been looking.  I didn't 
record much in HD and haven't yet replaced my usb-current-limit-hitting 
HD tuner.

I don't know if or how running an i686 system will affect matters.
