Take a look at Vizard's filter plug-in. That's documented in the Vizard help and may help with your first question.
For your second question, have you been able to get it to work with a single monitor in stereo using:
Code:
viz.go(viz.QUAD_BUFFER | viz.FULLSCREEN)
In the future please create a separate threads for unrelated questions.
There is an error with your closing code tag so the tags are not working. You should be using [code][/code]
