I tried with vlc. The "unsupported media type" files play in VLC, but they play terribly. The FLV one plays a few frames at the beginning and a few frames from the middle. The rest play the video but full of stutters and freezes. The video might be the wrong dimensions... I know the internal camera saves .mp4 video at 848x480, approx 3000 kb/s. Maybe try those dimensions?
