Despite the name "QuickStudy Videos: MSDOS Intermediate", this tutorial drags on for nearly two hours, and spends most of its time covering only the most basic DOS commands. It has a copyright date of 1995, but appears to have been recorded in 1993, and features MSDOS 6.0. It was likely produced on a Commodore Amiga, since you can hear the sound of an Amiga mouse being clicked during some of the transitions.

Transferred from a VHS tape, which claims to be "VideoLock™ copy protected", but shows no signs of having any copy protection encoding (nor does the U.S. Trademark Office have any record of any such named copy protection scheme). Its hifi audio track was so noisy that I had to revert to the linear audio track, and used a BSR DAK1 noise reduction unit to clean up the hiss. And the few seconds of the video being rewound at the end was not caused by me; it was actually recorded on the tape that way.
