Ok, normally we don't inform about various Microsoft security problems, because they are not related to our area of expertise, audio & video. But now experts have found a security hole in Windows Media Player v6.4, probably the most popular video player in the world -- most of the users prefer to use this, rather old, version instead of Microsoft's bloatware WMP v7.x.
