When the render finally completes, you get a 'save as' dialog box, I would save as AVI without compression, it saves having compatability problems with your media player. Set the image size to something small, say 150 X 150 pixels. Open the render settings, choose to render to file, as an animation not a still image, and as an AVI. For a first attempt, I would set render quality to 'open GL', it's MUCH faster than a software render.

When you're happy-ish with the result, SAVE!!!, then render. Each time you alter a frame, you have to set it as a 'key frame' using the appropriate button on the timeline. It won't necessarily look right on your chosen figure, arms passing through each other et c, so you will have to step through the frames using the timeline controls, and edit the pose at maybe half second intervals. You can run the animation from the timeline, it runs in realtime so may 'skip' a few frames to get by, but it should give you an idea of how it will look. Apply one to your figure, and the timeline fills up with stuff. Find some animation pose files, try the ones from I had a look today and the ones I used are still there. Load a character into the scene with as little extra stuff added as possible. You need to find the 'timeline' tab, at least that's what it's called in DS 1.5. You're going to have to start small, and build things up slowly as you learn what's needed.
