I bought and Watch the Rare video of national geographic on ‘Laser Disc” call incredible of human machine.
This very amazing stuff how show inside are body’s using advanced bio-medical equipment & Techniques.
Some use Special effect is this long before digital computer back then it’s all analog stuff they did using microphotography.
This show I give rating GV is stand for Graphic violence.
Now For this Laser Vision AKA Laserdisc review the video excellent no digital sound
Just Analog Sound is sound it perfect I copy off LD on to the DVD-R.
LD is way Better VHS Tape the DVD it had too much Digital video quality.
