Moviemaker for P800/P900 for Mac

From Makayama Media:

This software allows you to quickly create movies for playback on the Sony Ericsson P800 smartphone. You can take a movie from your DV-camcorder, from a website or from any other source and convert it into a super small mpeg-4 file, which is optimised for playback on the P800 built-in video player. Watch your favorite tv-show on the train or show your home movies to friends.The software can do a one-click conversion of a video file to a P800 movie. It's easy and fast and all settings are done automatically. The software dramatically reduces file sizes, so that a half hour tv-show fits onto a 32 Mb Memorystick. A feature film would fit on a 128 Mb stick. Advanced settings are available, enabling expert users to tweak and improve the video and audio settings.
