I can understand the arguments in both camps - on the one hand it is disappointing that cuts have been made, but on the other I understand why the cuts have been made.
I sympathise completely with those in the first camp - when TV 3 in NZ (owned by CanWest) played re-runs in the 1990's, they made horrendous cuts to all 120 episodes eg the Rita Moreno episode - Rita's first number was shown but then the first backstage scene, the Vets Hospital sketch and the second backstage scene were cut out completely, with the next scene being the Newsflash.
The comment "Some music rights are not available at any price. You may have Bill Gates' bank balance behind you, but if the rights holder refuses to grant you a licence, there's nothing you can do." is, I feel, slightly misleading. There will always be things available for use, it's just that sometimes the "studio" that releases the DVDs feels that it's too expensive for them to purchase the rights to use a song, even if it's only a 10-second sound bite.
A good example comes from the BBC's Doctor Who DVD range; a Fleetwood Mac song could be heard in the background from an episode transmitted in 1970. Unfortunately, the BBC felt that it was too expensive to pay the copyright holders the necessary sum to use that song, so it was removed from the DVD release.
At this moment in time I'm not really sure whether I'll buy this release when it's available R4; considering I used to gnash my teeth when TV 3 showed "butchered" episodes, I may ignore this release...but don't quote me on that.
