Windows Media Player (WMP) 11--which debuted at CES earlier this year and features a visually appealing interface, as well as impressive features and performance--is Microsoft's best jukebox to date.

As far as I know until very recently (a month or so) there was no way at all to watch BluRay on OSX. Now there is one but like with windows only through third party. As for Linux there will probably never be a BluRay playback software. DVD on the other hand runs very smoothly without doing anything on Windows 7 as well as OSX and Linux, at least most of them. I don't remember about Vista and XP, it has been some time. Which brings me to my next point, as far as I remember Media Player 11 is only for XP and Vista which is very unusual to be installed on a 'new PC'.

P.S.: This of course is only true for completely legal setups. No gray or black stuff.

Or do you really have BluRays that are not copy protected? How to format usb for windows 10 and mac.
