I originally posted this same problem in the Hardware section but I've tested it a bit more and it seems to be a problem that exists solely on Smooth Moves. So let me explain, when I try to do multiplayer on Smooth Moves the second remote will not be recognized. Pressing a few buttons to get it responding doesn't work, so the next option would be to re-sync it. I've tried that as well though and no sooner has the second remote been recognized that it has "un-synced" itself. I have tryed both my remotes as the second player and the same problem occurs.
Thanks in advance to anyone who can help me.
