I don't see this as a problem. Who uses DVD video anymore? Why should the cost of Windows be inflated by the licensing costs of DVD for a feature very few people probably use anymore. Video is downloaded or streamed online nowadays.
{raises hand} I still watch my DVD/BluRay collection, but I usually use my PS3 for playback.

Windows 10 is free, if you need DVD player software, suck it up and buy it. There are many 3rd party dvd software.
VLC player is free.

But I really liked Media Center while it lasted, and I still use it with my Happauge TV PVR on Windows 7.
Even if you buy Windows 10 (Pro on USB = $260), it still doesn't come with a DVD player.
