>What are you testing anyways. HDCD on computers?
Since Microsoft bought Pacific Macrosonics, they added HDCD capability to Media Player 8 which at the time being is a beta for WinXP. I got the beta player and installed it under WinMe and Win2000.
It seems to detect the above Austin Powers CD and add a little 'HDCD' logo to the player indicating it knows the media and is playing it back but I can't tell much difference on my system.
