I'm running my new Mac Mini with a Sony LCD TV as the monitor. I can't get the Mac to recognise the TV as HDCP compliant when trying to play iTunes Hi Def downloads. It is a fairly new TV (1 y.o.) and plays Blu-Ray just fine. It's connected via the display port to a HDMI input on the TV.

Ay suggestions would be welcome.

(This DRM really frustrates the actual consumer like me, who pays for stuff. The pirates don't seem to care)
