Turn off the XMP embedding options in the prefs and/ or the render settings. It's Adobe's own versioning nad metadata system as also used in other apps. the failure here is, that due to some bug it gets written for every frame when it should be just one set of data for the whole file, that's why files become so huge.
Thanks. It should probably be off by default when someone does the final render (with the Best Settings), because that stuff takes so much space. Just a thought...
And other people think that it should be on by default so that the information isn't lost.
If you would like to request different behavior, please fill out the feature-request form.
Todd, just curious, why would someone want that in a final render?
And, FYI in case of my 9-minute video, it added 9 MB to the mp4 rendered file and 10 MB to the wmv file. That is a lot of wasted bandwidth if it's intended for online use.

Not all exported movies are "final" versions for playback over the Internet. If you want to maintain the maximum amount of information in your files as they move through your post-production pipeline, then you can. Ifyou want to strip the metadata out, you can. Adobe Media Encoder CS5 provides a nice interface for stripping out and keeping just the parts of the XMP metadata that you want. See "Export and thin XMP metadata".
One example of including a large amount of temporal metadata in a movie is the creation of speech-to-text metadata so that the text of each word that is spoken is embedded in the file associated with the time at which the word is spoken. That can then be used further along the pipeline (even at playback in Flash Player) to do things like make the video searchable. There's an example of that in this article.
