i've tried it now:
my config:
- AMD X2-4400
- 2 * DVB [C + S]
- cpu+ mode
- libmpeg2, opengl + OSD Fade
- PAL-SD material (all 720x576 or below)
- Deint: kernel(2x HW), kernel

- GT6600 with 100.14.11 CS driver.
- xorg with UseEvents=true and Composite=disabled
- Display: CRT (1400x1050 at 85, 1280x960 at 100) DFP(1280x720 at 50)

at first:
xorg crashs approx. every 5 start or stop of mythfrontend (start == 
switch from menu to play-tv, stop==abort play-tv to menu). really 
annoying, i had to write this mail twice :(

0: /usr/bin/X(xf86SigHandler+0x81) [0x80c8631]
1: [0xb7eee420]

Fatal server error:
Caught signal 11.  Server aborting

don't known if this belongs really to mythtv. But trunk dont crash xorg 
and other opengl apps are working fine (mplayer -vo gl:yuv=4 and 

- OSD fading is choppy
- PIP window has wrong position, size and aspect ratio (but there are 
similar problems in trunk)
- mythtvosd is not working correct. On CRT video output stops completly 
during osd output, on DFP is really really slow.
- Kernel (2x HW) is not really as smooth as expected (compared to trunk 
with my own full framerate patchset) but smoother then 25fps video. Why 
only the HW Deints can be used with full framerate?
- sometimes mythfrontend crashes (segfault) but xorg survives.

summary, the new OSD is nice. OpenGL scaling is the same as xv scaling 
on newer NVidia cards hence i did'nt expect some quality improvements 
here. There are room for further improvements but it's a first step 
into right direction. Thanks for this.
