Windows 7 includes support for Dolby Digital Plus

I noticed this the other day as I migrated my main HTPC over to Windows 7, and shame on me for not even thinking twice about it. Part of the reason is that I prefer to just use 7.1 LPCM instead of passing through the bitstream, but unfortunately with HDMI and Windows 7, I have yet to figure out how to do this. Argh.


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).
