The MI2 CD version is just the floppy version with copy protection removed (which also removes lite mode since that and the copy protection screen is in the same "room") and with the ability to run it from CD while storing save games on the HDD. Unlike MI1, there are no separate EGA and VGA releases of MI2.
That video you posted up there just runs MI2 in EGA mode along with the PC speaker soundtrack, which lacks most of the music, but where the end credits medley is different. The Adlib and MT-32 soundtracks are both complete.
