On Tuesday, Microsoft refuted earlier reports that it plans to introduce single-play DVDs aimed at curbing music piracy. A Microsoft representative told me there is no single play DVD initiative at the company, denying a report that first appeared in "The Business."

"It appears there is considerable confusion coming from \[the\] article in The Business about features within Windows Media DRM that allow for single-play of promotional digital materials," a Microsoft spokesperson told me. "This has been an option for content owners to use for some time with the Windows Media format--but not for the MPEG2 format found on DVDs. Windows Media DRM technology allows for a wide range of business models and scenarios, but it's important to realize that this is at the discretion of the content owner to implement and that the market will dictate whether or not these features are compelling enough for consumers to make a purchase."
