Not sure. I forgot about this message, and I just put in my 5200 to test
something. The 5200 is an NV34, and I don't seem to have any OSD
problems with it either.

See attached, although I am using XFree.

Actually I think it was the other way 'round, trunk changes were merged

I think I found the solution to that problem, thanks to another post in
* nvidia-settings (X In X Server XVideo Settings:
X Video Texture Adapter|Sync to VBlank (Highly important!)
_ Video Blitter Adapter|Sync to VBlank
In OpenGL Settings:
X Sync to VBlank
X Allow Flipping.
* mythfrontend's Setup|TV Settings|Playback
X Deinterlace playback | Bob (2x framerate)
Preferred MPEG2 Decoder: libmpeg2 (I can't say I've seen a difference
here between this and Standard.)
X Enable OpenGL vertical sync for timing (RTC timing, used when
unchecked, also works fine, as long as dev.rtc.max-user-freq24
appears in /etc/sysctl.conf)
X Enable realtime priority threads (irrelevant, as I haven't actually taken
the steps to let mythfrontend run in realtime)
_ Use video as timebase
X Extra audio buffering
What happens with different settings:
* _ Video Texture Adapter|Sync to VBlank (Video tearing, so that the
top 1/6 of the picture appears slightly behind or ahead of the rest)
I made my settings the same as above, and now I don't have the tearing at the top of the picture.
