You'd think Nero would kindly provide a link in the player to a site where skins can be downloaded. I can't believe no one's made any. I bought Wallace Wang's book about Nero 6 Ultra, which showed a nice (futuristic) one. He didn't say where it came from, of course.
In fact, With the Nero skin I see on my Nero audio player, I can't even figure out exactly what all the buttons are. I'm not done examining the section in my book dealing with that player, mind you.
