Real-life MPEG and VC1 HD samples do not decode in real-time with this setup (H264 works fine even for bitrates higher than level 4.1 and using de-interlacing).
Looks like a cpu bottleneck since MPEG and VC1 are partially accelerated on this GPU. For such a cpu, i think a G98 (with complete acceleration of MPEG, H264 and VC1) would be a better choice.
