Default Re: VDPAU and OpenGL Textures?

I guess when you mix vdpau with opengl using glx_ext_texture_from_pixmap a memory copy needs to happen. Is it possible to prevent this? A friend of mine is considering using nvidia hardware in a broadcast product in which he in the end wants to render 4 720p streams simultaneously. I know right now vdpau offers only one stream, but would the hardware be fast enough for this? (a pci-express 2.0 link would likely be required for the bandwidth)
