HDMI DVD Player to Projector Problem? - dvd player with hdmi great hdtv picture

This new projector, DVD Player NEW. I bought a HDMI - D-sub to go from DVD (Sigmatek XS-700) on my projector (BenQ MP611c). I get no screen. Manuel says:

PROJECTOR Manual: When the projector to a High Definition TV (HDTV) tuner, the following rules
are supported: 420i / p, 780i / p, 1080i

MEMBER DVD PLAYER SETUP: Setup-compatible HDMI display: 420i / p, 780i / p, 1080i

If I leave the DVD player (Sigmatek XS-700) to the projector through [to the D-SUB-COMPONENT] - Works fine and displays 420i / - p good image.
800x600 I am connected to the laptop and it works well, great film. (IC IC-cable connection)
S-Video and composite, all work well without problems, both the DVD player and projector. Your new kit new everything.

My problem is this: If I have a connection to an HDMI cable for HELLO DVD player and projector no signal at all. But works also all other cables. What am I doing wrong? PLEASE HELP - AT Wits End
