[mythtv-users] OpenGL sync: No effect on newer NVidia cards?

After exchanging my FX5200 for a 7600GS, MythTV's OpenGL sync seems not
to have any effect anymore.
I am outputting PAL to 1080p and got very visible tearing.
I was able to workaround/fix this, by enabling XV-Texture sync in NVidia
settings. But then I had high CPU and so I also added UseEvents to
xorg.conf which fixed this.
My question is: Why do I have to enable XV-Texture Sync (OpenGL Sync is
supposed to prevent tearing) and why does it help at all?
- Celeron 2.6 GHz
- AGP 4x board
- NVidia 7600GS
- Myth 0.20 fixes
- Kernel 2.6.20
- NVidia 9755
