Configure options not picked up

When looking at the build log, you'll notice that certain configure options are not picked up by the MythTV configure script.

Build log: http://launchpadlibrarian.net/12220720/buildlog_ubuntu-hardy-i386.mythtv_0.21.0%7Efixes16259-0ubuntu1_FULLYBUILT.txt.gz

Relevant parts of the configure call:

CFLAGS="-g -O2 -fPIC -DPIC" ./configure --prefix=/usr -
  --with-bindings=perl --enable-opengl-video \
 --enable-xvmc-opengl
        --compile-type=profile --tune=pentium3 --cpu=pentium3 --enable-xvmc --enable-xvmc-vld --enable-xvmc-pro

Now let's look at the output of configure:
XvMC support yes
XvMC VLD support no
XvMC pro support no
XvMC OpenGL sup. no
XvMC libs -lXvMCW
OpenGL video yes
Fribidi formatting no

As you can see, some XvMC options are not picked up properly. XvMC-OpenGL should probably stay disabled (remove --enable-xvmc-opengl) because it's experimental and upstream does not really support it.

Regular OpenGL video is still somewhat experimental and can cause segfaults under certain conditions IIRC, but I'd suggest leaving it in because it's a nifty feature. According to Stanley Kamithi, it can cause problems with XvMC and DVD playback: http://svn.mythtv.org/trac/ticket/4767#comment:1

Not sure what to do about XvMC VLD/pro support. I think they was some discussion in #mythtv the other day (with Cardoe, the gentoo maintainer) so you probably want to check your channel logs for that.

Fribidi formatting is used to support RTL (right-to-left) languages. It'd be a good thing to have that.
