I can encode the capture into mpeg 2 and post it here. In a mean time I can tell you that it was LD VE, but I wouldn't say a torture-test. If you remember VE LD, they show how someone is trying to fix his home equipment with a screw driver and has achieved shortage doing it - everything goes white and then the next scene shows a house at night. So during the dark scene it would take a few frames to adjust the darker scene: it goes bright then darker, darker darker, back to normal. So it was not a test pattern but rather a real footage.
