Been coveting that Blu-ray edition of A Clockwork Orange or The Dirty Dozen, but don't know what to do with the perfectly fine DVD version you've already got sitting on your shelf? Warner Brothers has set up a website called DVD2Blu, through which owners of selected WB DVDs can receive an authorization to mail in the old discs for the fancy new ones. The cost? A minimum of eight bucks per title, plus shipping. So, not a bargain, exactly. But if you've got a mania for order and can't stand duplication, this could be just the service you need.
