I just found this last night, and it is pretty good. All it needs is an EQ and colour controls for video. I also like the fact that you can take sequence clips, put them into a folder, add .movies extension, and it'll open them all as if it were an archive within clipshow
I also like the look of the GUI. To me it's like a crossbreed of QT/iTunes/WMP, all in one.
I always liked WMP's integrated sidebar for playlists.
