Are the episodes on the DVD in letterbox or just 4:3?
The DVD released on 7/3/2001 is in 1.85:1 aspect ratio & enhanced for anamorphic screens.
The details are on this DVD review:
"V" is presented for the first time ever in anamorphic widescreen with an aspect ratio of 1.85:1. To say that this transfer came as a surprise would be an understatement as "V" has always been seen in the standard 4:3 television format. But Kenneth Johnson had anticipated a potential foreign theatrical release for the program and decided to film it with a widescreen framing in mind. In comparing the full screen and letterbox versions it's clear that the widescreen transfer omits a bit of top and bottom image for the sake of the wider view but at no time do these shots look forced or out of place. This is the way the director intended the show to look and he personally supervised the transfer process so I'm satisfied that this is indeed the way that "V" was meant to be presented.
