[mythtv-users] nvidia 6200tc tearing and high xorg cpu usage seemingly fixed

I have this "tearing" issue on 1280x720p wth the same hardware you use
(A64, 3400+, "slightly overclocked", nVidia 6200-based video card).
I've been running the 8774 driver. When I installed the latest 9xxx
driver, the tearing in the upper area of the screen went away - just as
you mentioned...I was happy. However, MythWeb began to crash the system
when I clicked on "Backend Status" (it locked up X; I could ssh in but
couldn't kill the process, or even reboot cleanly - had to resort to the
reset button). The rest of MythWeb worked OK. This went away when I
downgraded back to the 8774 driver (but of course, the tearing came back,
and it's beginning to annoy me again). Anyone else seen this issue?
I suppose I'll wait for the next nVidia driver to see if this clears up.

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.
