The last time MPEG2 decoding posed a problem was in the PII-300 days.

If you want to speed up VMR7/9 a little, especially when subtitles are
shown, disable FSAA from within the nVidia driver panels.

There may be. However, what would be the real world value of such a
benchmark? There are really just two useful metrics for video decoding: # of
dropped frames and % CPU utilization. If with the Purevideo decoder you
currently get no dropped frames in any video you play, and the CPU
utilization stays below 30%, there is absolutely nothing to be gained by
overclocking.
