The sRGB and extended colour support is
only support in VDPAU playback
mode. I hope to add it to OpenGL
output one day...

You go in the setup.

I described how
to set it in those two
changeset:
http://svn.mythtv.org/trac/changeset/22431
http://svn.mythtv.org/trac/changeset/22495

The
easiest way to set it up is to delete the 3 default VDPAU
profile
(VDPAU Normal, High Quality and Slim) and restart
MythTV

Then you go back in the setup ; Utilities/Setup ->
Setup -> TV
Settings -> Playback -> Playback Profiles ->
Custom Filters
Add the filter vdpaustudio to enable studio
levels
vdpaucolorspace=auto should already be in the list of the
custom filters.

So typically your custom filters line will be
something like:
vdpaucolospace=auto,vdpaustudio

You have to
edit all entries in the VDPAU profile.
If using VDPAU High
Quality, there's only one
but in VDPAU Normal there are two ; both
need to be modified.

One more question.

In this post. http://svn.mythtv.org/trac/ticket/7307

you say use studio,colorspace=0 
but here you say 
vdpaucolospace=auto,vdpaustudio should work.

What is the difference?  I am just
trying to understand and hope I don't come across wrong.
Is there some sort of documentation
somewhere?

Again thank you.
