Honestly WMP is a bare minimum DVD playback experience, and most people don't even know it is bare minimum experience as they don't even know how to watch DVD using WMP. WMC may be ok, but, we really need to consolidate the experience to Metro to reduce customer confusion.
I'm not going to get into the argument over whether the DVD codecs should be included. It's been done to death and if you don't like it, it's hardly the end of the world. It's not like they're shipping bobcats inside Windows packaging...
Except to respond to one point in the above, the way I've responded to it before. WMP doesn't suck for playing DVDs, and the less 3rd party suckware on my computer the better.
Seriously, which is better:
At the end of the day if I have to pay for the codecs, I have to pay for the codecs (or use VLC), but WMP sucks less than PowerDVD et al. End of.
