The cinefx project covers a group of open source digital content creation tools for media playback, encoding and editing which include cineplay, cinecode, cinemix and ncode
It's not cinefx, it's just a video player called "CinePlay".
Will fork to csharp maybe
The previous comment posted was 33 days before mine. I, too, clicked on the link for the 9MB Cinefx, and got the 22MB Jahplayer, which doesn't open anyway. Cinefx.org's page has today's date on it, but apparently the date-bot is the only thing that shows up there anymore. No fixed link, no redirect, no explanation, nothing.
