This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.

This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?

Just post some stuff and don't spam.

Later Laserdiscs (and VHSs) had digital audio embedded in the analog audio stream the same way the GameCube and the Wii (and some N64 games) did it with Dolby Pro-Logic. But the video was always analog. IIRC the first widely available digital video format was Video-CD but that never took off in the west.
