Hi. I'm very new to motion (whichever version is part of FCS2), and getting to know the basics of it. Run into a problem trying to export a project recently. I want to use "export using compressor", because it allows me to use the x264 codec which does NOT show up when I try to export directly from motion. Anyway, even though I have a project in and out, (even checked under edit/project properties, and the out is where I want it), for some reason when I export using compressor, the resultant file is much longer than it's supposed to be. It's like it ignores the out point in the timeline and keeps going for a while. If I export directly from motion, and check "limit to play range" or whatever that option is, it works as it's supposed to. Guess I don't get why the compressor option ignores the out?

Try exporting to a frame based codec like ProRes and see if the same problem occurs. If not, it means that Motion and non-Apple codecs like x264 don't play well together.
