Super seems to work very well! Some of my videos have AC3 audio, and Core Player doesn't support it yet (they don't have the licensing - since it's no longer open source), so I've encoded the video to mp3 audio, and avi video w/divx codec.
It works great!!!!
Super © has my vote!
EDIT: Okay, I tested a video on TCPMP, and it played fine. I tested the same video on Core Player, and the video wasn't smooth. Audio was good however. Not sure what the problem is.
