Do I spot a hint of jealousy?
Sometimes we in the UK get a DVD first, sometimes (most of the time) the US gets it first. Also sometimes other countries like Germany, Australia and France had had releases before any other countries. It depends on what other films are out and about at the time, because all countries have different release schedules for theatrical films and DVD releases they appear in different places at different times!
Know what I mean?
For example The Us is getting Bambi at the start of March, now here in the UK we are getting Mary Poppins and Pocahontas at the start of March, so it wouldn't really make much sense for it to be released then because there would be three disney special editions all out in stores all at once, which means not as many are going to be sold, because people aren't going to be able to afford 3 all in one go.
It is arguable that Bambi could then have been released towards the end of March, to give a couple of weeks for Pocahontas and Mary Poppins to sell. However the problem there would be that "The Incredibles" Is being released at the end of March and Disney would not want it's 2 potential biggest sellers of the year competing with each other at the same time!
Bambi could have been moved to April, but then it would be up against the special editions of Alice in Wonderland and Dumbo. In May it would be up against the special edition of Tarzan and if it was then moved to June it would be really close to Cinderella in the Autumn, and Disney probably wants to keep it's two platinum editions at opposite ends of the year.
Now in the US you have already had Mary Poppins, Alice in Wonderland and Dumbo, and Pocahontas is coming later in the year, so BVHE US can afford to put Bambi back a month, because you have different releases to us. The same thing applies to other countries too, such as Australia and France which got the Mary Poppins, Lilo and Stitch and Pocahontas 2 disc special editions last November!
It's nothing personal against the US, it's just simple strategy, juggling the releases so they don't coincide with each other!
Oh and one more thing...
Ha, Ha! we got Bambi before the US/Canada!

Only Joking!
