You may be able to play video's on your palm straight out of the box. Most Palms over the last couple of years have come with "palm media" which handles both photos and video's.
Check under preference and see if you have a multimedia sub group. Within that group you should have a 'pics&videos" icon. That's the magic bunny. On your PC you should also have a "videos to go" option. Apple users to do not get the the video to go item though do have a dropper that allows transference of videos from macs.
