I haven't tried Orb on my Wii. I tested it a bit between computers and found it was rather slow, so I uninstalled it.

I already had another way to get media from my computer onto my tv/stereo so I haven't look very hard for this kind of thing. There is a free one Wii Media Center X that I look at once in a while, but development is not proceeding quickly, if at all.
