This distribution includes some support for GL rendering of video frames.
This provides really high performance and high quality scaling playback.
In its current state, it is still somewhat flaky on some configurations, so it
is disabled by default. If you have hardware support for some OpenGL
implemetation, and wish to see what Xtheater can do, then run configure with the
option "--enable-gl".
This enables gl support in the smpeg plugin only, the wm plugin does not
currently have working GL support.
After this step has been done, the options should become available in the
"Plugin Options" item in the "Options" menu.
If you want to go all out, click in the item "use gl for all frame rendering".
Also, you may wish to set the GL_Fullscreen resolution to something suitable.
The default is 640x480, but I usually set it to 1280x1024, to avoid a
modeswitch.
