Here is the beginning of one of the GM laserdiscs, you will here some FSK audio at the beginning, that is to program the CPU in the pioneer PR-7820 to go into "interactive mode" This copy is from a defective pressing, that was then used on side 6 or the dead side of Jaws. There where a lot of problems with defective pressings because MCA/DiscoVision thought that optical video discs could be pressed under the same conditions as LP records.... WRONG! https://youtu.be/zG5S_NWLwIQ Sent from my iPhone

Here's what one of the discs did in my player. When the machine reached a bad spot in the disc it would give up after a moment. If I used the jog control sometimes I could skip over the bad part:

This was one of the older discs, but despite having some rot it still played acceptably:
