What would you say to fans outside America - who probably have all the VHSs - about buying the DVDs too?

Well, obviously you�ve got the quality of DVD which is the first and foremost thing in terms of audio and video. Tapes degrade over time - if somebody is a die hard fan of the series they�ll want to get it in what is basically an archivable format.

Then the other benefit of DVD is the added features that you can put on, that you couldn�t put on to VHS tapes. Things like the commentaries and the extra material that we put on DVDs. The talent involved in the production of the shows wouldn�t really be interested in doing [those] for a VHS release. DVD has changed the way they perceive the home entertainment market.

Then the other thing is that you can have the entire season in a box as opposed to a 'best of', or a themed series, or "Here�s six tapes of the 12 shows of a season which had 24 shows in it" - it�s incomplete.

There�s something nice and complete about having it [all]. I�ve got the entire season one Buffy in front of me in a box that�s less than an inch thick, that takes up hardly any shelf space compared to the same thing on VHS [which] would take up nearly a foot. So there�s a number of reasons. I�m a big fan of the DVD format.
