HDMI to DVI Cable

If I use a cable with a DVI head at one end and HDMI at the other end, would this cancel out the benefits/advantages of both formats? The cable would be connecting the HDMI output of the DVD player and DVI input of the display projector.

Any advice from knowledgable folks would be much appreciated.
Not really. HDMI has a slightly longer range, but when connecting to a DVI device, the interface should be backwards compatible--you won't get audio, however, which is part of the HDMI spec but not the DVI spec. The only times I've had problems with DVI/HDMI cables was when I used a DVI switcher. I had a mix of DVI and HDMI sources, a monitor with a DVI input, and the DVI switch in between. Everything worked fine until I switched out the monitor for one with HDMI, then the HDCP started messing up. Turns out if an HDMI source is talking to a DVI input, it will downshift to be DVI compatible. But, then I switched to HDMI source talking to HDMI input, and it stayed in the HDMI format--except that the DVI switch in between wasn't passing all the HDMI signals. Anyway, moral of the story is buy an HDMI switch, not a DVI switch.
Thanks for your response. I reckon I won't be using any switches and hence may not encounter what you've experienced. It looks like DVI is getting less favoured nowadays with HDMI sources and displays getting more popular.
You will lose the audio benefits of HDMI if you use a DVI end, as HDMI carries the audio signal but DVI doesn't.

With the upcoming HDMI1.3 format you'll lose the potential to benefit from the higher resolution format.
