In what is hopefully one of many new announcements about Windows 7
leading up to its launch, Microsoft has added support for Dolby Digital Plus
in most versions of Windows 7. This is good news indeed, as the Plus version of Dolby Digital not only supports higher bit rates than the classic Dolby Digital, but it also offers better sound quality than its older brother at the same bit rate -- it is not lossless like Dolby TrueHD though. The other key reason why this is essential to Windows 7 from the Media Center perspective is because premium content providers around the world use it (like France, Italy, Spain, Sweden, and the United Kingdom). Dolby also confirmed that this support includes Extenders for Media Center
which makes it all the more useful.
