Dear Mr. and Mrs. Microsoft, and all the little Microsofts.....

You won't like this, but you need to know: KPLU's player works better than your Windows Media Player in Win-8.1 Pro Preview.  Your WMP seems to have a little buffering problem, and cuts out momentarily every few minutes. This player of KPLU's doesn't hiccup like that. It plays very smoothly, and I can't believe that's just because I'm a subscriber, because the player doesn't know that. Only the folks at KPLU know that. So I guess what I'm saying is: Please check WMP for a buffering problem when being used in Windows 8.1 Pro Preview. 

And you don't want to know this either, but my favorite player is Winamp! Why?
Because amongst its other great features, it has a windowshade mode that fits it neatly into a title bar of the browser or other windows, or just lets you keep it
out of the way up along the top of the screen. Yours doesn't seem to have that particular feature, and I have to ask "Why the hell not?" If Winamp has had that feature for years and years, why not Mighty Microsoft? One of the reasons for these new upgrades is to introduce improvements, right? So, improve it, please!
