The Remote Wonder will work with any application so long as it has a standard bundle identifier. MPlayer unfortunately doesn't, but it's easy enough to remedy. I think I'll include instructions on how to do the modification in the release notes for the upcoming version of RW. I've already got profiles made for VLC and MPlayer and a bunch of other programs that I'll throw in as defaults with the next version.

The new (forthcoming) Remote Wonder software also supports all three models of remote: original bulky RW, sexier but with horribly small buttons RW2, and the new smaller but with more buttons RW-Plus. And a brand new interface (which like the last, I also designed )
