Well, what are you trying to accomplish? Are you trying to compress it down to something for the web, or...? You need to use Export > QuickTime Movie and then select a compression codec and set it up so your resulting file will be smaller. What codec and settings you should choose depend on what you're trying to do.
I just want to play the DV file. But when I run it through this video program I have, it plays as though the high-quality setting in QT is off. You can see how videos look by going into the movie properties and turning the High-quality off.
So in order to play this video with it in, I have to open the DV file in QT, then just save it as MOV. It's still the DV codec just with a MOV container. But whenever I do that, it doubles the file size.

Quicktime defaults to the animation codec (a lossless codec, which is why you are getting big file sizes) when exporting. You need to change the codec to DV/DVCPro NTSC.
Out of curiosity, what's the difference between a .mov and a .dv file? Is there a lot of quality lost by having the file in iMovie and then sharing it as a full quality video (in order to get my file out of iMovie but with the subtle trims I've made to the footage).
