Here is a little video recorded of a USB13700 board driving a Planar EL320.240.36HB display using LCDStudio.

As it can be seen there isn't any of the corruption ("SED snow") seen that happens with parallel port connected SED1335/S1D13305 controllers.
Also the framerate is much higher and cpu usage a lot less than with parallel port lcd.
Using a real video camera instead of just the video recording option of a digital camera would allow capturing the real thing as now the framerate seen is limited by the capture rate of the camera.
edit:
Here's also a lower quality version for viewing straight from YouTube:
