DVD movie will not play video

I'm using the 64-bit Beta flavor and cannot get Windows Media Center nor Player to get a commercial DVD movie to play. I can hear the audio and see the select "play" title only. Anyone else have this problem or a remedy????

My specs are on my profile>about me section. Thx

did you try VLC?
VLC media player - Overview
if it works with VLC it's caused by a missing codec (though I thought codec for playing dvds was shipped with windows).

Actually, I've been using VLC. That plays fine. So it's a codec error somewhere. I wonder if one of my programs replaced the windows default with something else???

Most likely a codec issue. Check out this page for more information about codec packs:
Windows 7 Codecs | Windows 7 Center

Or you can just grab the codec pack download straight from this link:
|MG| Win7codecs 1.0 Beta

It's from shark007, the same guy that made the Vista codec pack so you don't have to worry about it being unreliable or anything like that =)
