Try Start8, Pokki, or Classic Shell to get Windows 8 back to somewhat like Win7. I use Pokki and it's pretty great.

If he has Windows 8 Pro, you can get Windows Media Center for free here: http://windows.microsoft.com/en-US/w.../feature-packs That will give you DVD playback.

If not, VLC will work: http://www.videolan.org/vlc/index.html
