>For the non optimized display settings in Mythtv I don't see any
deinterlacing options. OpenGL in Mythtv has deinterlacing options, which I
can deactivate.

>Maybe I have to make a step back. I tried several times to get OpenGL
working and hoped with newer Installation of Ubuntu and xorg-edgers that the
following errors got fixed. But they still exist:

VAAPI: Invalid display

Try to go the VAAPI was. The kernel provides the wrong Vendor, see detailed
glxinfo output below.

OpenGL vendor string: VMware, Inc.

Which I could fix with an updated to head kernel.

However with VAAPI, I get a GPU hang. I will investigate and report it in a
new issue.

I don't have a xorg.conf.

What can be wrong here ?
