It would appear that the advertising claims for the Western Digital My Book(TM) World Edition(TM) II which include: "Listen to the music on your My Book World Edition drive while you're on vacation." and "Securely access and edit your files on any computer." and "Get files from home while at the office." may be false.
This Support Page specifically says: "Due to unverifiable media license authentication, the following file types cannot be shared by different users using WD Anywhere Access." Which means, of course, that if you have a great new multimedia demo of something which falls into the category of "Offer your clients an easy way to access business documents, designs, and artwork. Eliminates the need for a separate FTP server." and it's in one of a LONG list of "forbidden" formats, you're out of luck."
