Well, I found the time yesterday (in the drunken hangover haze that is
New Years day...) between the Rose Parade (horrible horrible coverage
this year =( and the plethora of college football to upgrade to the
9xxx series drivers and apply the "UseEvents" option.

WHOOPEE!!! tear-free low CPU use 1080p playback! I even have Kernel
enabled as my deinterlacer and was able to get through some of the
higher movement scenes in The Two Towers 1080i without ever hitting
100% CPU usage on my Athlon64 3200+ (slightly overclocked, something I
am now playing with...).

I'd say overall this driver upgrade is a great improvement for folks
with HDTV capable frontends, I'd recommend at least trying it even if
you don't have any issues with the old 8xxx series.
