What do I do with DNG files?

I've been handed 2 DVDs, with some 4 GB worth of DNG files (500 or so, 10MB or so in size each) shot by a professional photographer. I'm supposed to find one group shot out of those and use it in a video I'm working on. Nothing on my computer seems to know what a DNG file is. I have PhotoShop 7, and it doesn't know.

Vegas 6 will preview them and put them in the timeline, but it claims they are 256 x 170 x 24 TIFF (for a 10 MB file!) So does irFanView.

Is there some sort of converter to make these into a format I can deal with? I suspect that a 10 MB file has got to be bigger than 256 x 170.

Is it possible these are PNG files?

DNG is a new RAW image format being promoted by Adobe. Here is a link to a .PDF file that explains it:

There is a plug-in available from Adobe that lets Photoshop CS and CS2 handle these files. Here's the link:

Yeah, but Photoshop 7 doesn't support it. Sigh.

FYI: Found out that irFanView has a new version, with a plug-in that does support the .DNG format. I was able to load the images into that (turns out they're 4310 x 2866) and down-convert to something a bit more manageable.
