My suggestion for that underpowered machine is to purchase a nVidia 8400
or higher graphics card and use one of the VDPAU enabled versions of
mythtv. It will play fine with your other systems and will let you play
full HD with only a ~5% cpu load. Myth will automatically downscale the
HD programming to fit your screen resolution so it will have the same
effect as trying to set up mythstream to do the work for you. Its my
understanding that mythstream cpu usage to real-time convert a video
would be fairly high, perhaps higher than your cpu can support.
