And there is always the OpenGL option if VAAPI or VDPAU give you trouble. I'm using a low end i3-3220 with HD2500 graphics. I did have to create a custom OpenGL playback profile, since the HD2500 couldn't handle the deinterlacing options pre-configured for the "OpenGL Slim" profile. I'm happy with the results on my 32" 1080p bedroom TV.
