I found a channel on YT featuring full rough cuts of TNG episodes, digitized from VHS tapes. These are the temporary cuts before the final ones, having no post production effects included (no sound effects, no visual effects).
You can hear the original athmosphere on the sets during the shooting. Especially "funny" are the scenes in 10-forward, where all the extras are moving their mouths but dont say a single word.
