I read your article on high definition (HD) TV with interest and would point out that just because your display device is HDCP aware doesn't mean it will work.

I have a Toshiba (aka Infocus) MT8 DLP projector with all the latest firmware that supports HDMI/HDCP. When I replaced my DVD player I spent a little more and opted for the new Panasonic DVD-S97 player that also has HDMI and even Faroudja DCDi. 'Wow!' I thought 'this is going to be great'.

Plugged it all in... nothing. No signal. The DVD player reported "HDMI connection  error".

I spent months trying to get it working and eventually gave up and reverted to analog  component. I tried each of my components with a friend's setup - and  each worked. I sent both the player and projector back to Toshiba who said it all worked fine - but then wouldn't/couldn't tell me what cable they used.

To make it  worse, the average hi-fi shop salesman knows nothing about digital technology and the frequent misadvice and sometimes even plain B/S is hard to believe.

In this case I suspect that like all standards, there are different levels of conformance between implementations and that my DVD player and PJ simply weren't compatible.
