Windows A curious network performance reduction noticed by many Windows Vista users of the 2CPU forum that became the talk of Slashdot last week has been identified as having been caused not by DRM, as Slashdot users expected, but by a curious prioritization 'feature' of Vista that's intentionally biased toward Media Player at the expense of network and system resources.

HDCP and HDMI Video/Audio in Vista is encrypted.
The CPU has to do lots of extra work to encrypt/manage the data that is sent down internal busses. This was not a feature of XP.
