George Romero's Martin, 95 minutes (Anchor Bay) vs 90 minutes (Arrow)

[AllNight]

I've searched and not found any answer to this.

Some DVD's of George Romero's Marin are 1:34:41, like the Anchor Bay and Lionsgate discs, while others are 1:30:49, like the Arrow discs.

Sites like DVDCompare only say that there are "no cuts" on any of these discs, but clearly that is not the case.

I have verified with people who have each disc that each disc starts and ends with the same title and end credits sequence (i.e., there' not some 4+ minute long intro or something on the 95 minute version).

Does anyone know what is actually missing in the 91 minute versions?
