They're the same thing. HDMI is just DVI + toslink in one cable, and some completely pointless encryption garbage tossed in to complicate things needlessly... But that's Hollywood for you.
So long as you don't need audio, DVI will give you the exact same picture quality as HDMI, and so long as you don't need surround sound audio you can just get a 3.5mm to composite audio adapter cable for sound. Sure, it's not as tidy as the all-in-one solution of HDMI, but it will work just as well for non-surround sound audio. I forget if the MacBooks have an optical (toslink) audio output or not, but that would take care of the surround sound audio if they do.
And you should maybe check a bit closer. There are three kinds of DVI, and a lot of video card makers use one that normally can do either analog or digital video, and use the extra pins to transmit the audio portion for HDMI via a special adapter. I can't say for certain of the MacBooks do this, but I'd suspect the MacBook Pro probably would. But there has to be some way for the audio to be routed to that port, otherwise a DVI to HDMI adapter won't do you any good.
Check Apple's accessories for a DVI to HDMI adapter and see if it mentions both supported models AND whether or not it carries audio as well. And if in doubt, call up Apple's sales people and ask them. They overcharge like you wouldn't believe for that stuff, so the least they can do is track down the answer to your question.
