I developed my own MaxMsp/Jitter patch for VJing. Right now its pretty basic; it mixes video and applied a trippie blur effect, I am using a Vestax VCM100 to control the patch by Midi. I plan on optimizing it and making it more versatile by incorporating an easy file viewing system, different types of video blending effects, video effects, live camera input, Wiimote Control, generative Jitter graphics, beat detection, Ableton Live syncing, and OSC networking so I can DJ and VJ at the same time using two computers (one for audio and the other for video), and more. I will release the patch when it is ready!
