I guess what I meant was playing a DVD from the Mac (or any other machine for that matter). I realise that this is intended to be a business projector but I am interested in it for its form factor too. I'd would want to carry it around to friends also. At home it is intended for photo viewing and ... the odd DVD movie. Any chance you can throw a DVD into your computer and give it a go? Thanks again for your valuable comments.

Well, we ended up buying the Casio XJ-S30, which is the same projector as the S35 but without the USB port and wireless capability. My partner and I decided it just wasn't worth the extra $500 or so for these extra features, as it's unlikely we'd ever travel without our laptops and the wireless capability (which would cost another $150 for the transmitter) would come in handy on only very rare occasions. We had our first client presentation today. This projector is a real gem! It's super-bright and sharp, and there were no issues around the Mac's native resolution. We set the PowerMac up to see the projector as a secondary display and set its resolution to 1024x768. The image was very crisp. This also let us display the slides on the wall while cribbing from our PowerPoint talking points on the laptop. Very handy. Unless sunshine is streaming into the room, Eco mode delivers an image that's plenty bright. Running in Eco mode puts fan noise down to a whisper, which is nice in smaller presentation settings. The only quibble I have about this projector is the cost of the bulb, which retails for $500. But since I have seen it available with a street price of closer to $350, even this isn't as big of an issue to me now. All in all, this is a sweeeet piece of technology. It performs like a champ, and its sleek design gives it an added cool factor. I also love that it's a featherweight, and is actually about 2/3 the size of my laptop. Casio has a real winner here. I highly recommend it.
