video help
 

hi...im trying to add a video to my application with the following code:
[code]
import viz

viz.go()

myroom=viz.add('room.wrl')
#Create a texture quad to display video texture
quad = viz.add(viz.TEXQUAD)
#Create a transform to scale coordinates to size of video
xform = viz.Transform()
xform.setScale(640,480,1)
#Apply texture matrix to quad
quad.texmat(xform)
#Create a video texture of type viz.TEX_RECT
myvideo = viz.add('video.mpg',viz.TEX_RECT)
#Apply video texture to quad
quad.texture(myvideo)
[\code]

and im getting the following warning..wats the reason?

sorry forget to post the warning..


Warning: TextureRectangle::apply(..) failed, texture rectangle is not support by your OpenGL drivers.

This means you either have a low-end or very old graphics card. Make sure your graphics driver is up to date. If you still have this problem, then you can work around the issue by resizing your video dimensions to a power of two (16,32,64,128,...).
