The simple answer is to use the Apple Intermediate Codec version.
The ProRes 422 version is superior to AIC, but if you only use iMovie, you are unlikely to get the benefits of its superiority.
The only reason you have ProRes 422 as an option is that you have FCP installed. If all you had was iMovie, ProRes 422 would not be an option.
As you probably know, in the future you can import directly from your camera (or through a card reader) and you will not have to worry about all this conversion.

Sounds good, thanks. I'll convert the files to AIC (using one of those programs), then delete the MTS files - given how much more I use iMovie (90%+ of the time) sounds like preferable to ProRes (even through I have FCP installed).
