I finally watched the video. 27 minutes of video with about two hours of narration. My ears were exhausted at the end of it.
The guy I work with most of the time boosted his income very nicely for a few years by installing AC-3 decoders inside LaserDisc players.
Fascinating video and worth knowing about. Thanks!
