Lo and behold...
I found an old box with a VHS tape labeled MV3. I don't even want to play it in fear of damaging the contents. When I can get to my buddy's place, I will try and play it / digitize it on professional equipment. If I succeed, then I will try and make what I have available, but for now I don't know what kind of quality we will be looking at.
By the way, I did some checking around, and in LA, MV3 broadcast on KHJ channel 9. I saw KCOP channel 13 mentioned on another post as well, but that is not correct.
Cheers
