I don't think the DVD codec is installed on the beta, probably for licensing reasons. You will probably need to install a third party codec.
Actually, I think it is installed. When I pop in the DVD disc, Windows Media Player shows the FBI Warning Copyright Notice after which it wouldn't do anything anymore.
I select "Root Menu" and nothing happens. The DVD drive seems to be struggling trying to read it.
So I thought the DVD is damaged or something.
Boot myself back into Vista and try to watch the DVD again, and it works without any problem.
Do you have an NVidia video solution? If so, you might want to check Windows Update to see if there's an optional driver update available (one was deployed yesterday).
I don't have nVidia video solution, and I updated everything from Windows Update already.
Just base Windows 7 Beta installation with Windows Updates applied.
I can't think of a way how to troubleshoot this problem.
I use a DVD burner drive that is about 2 years old with nVidia GeForce 7800 graphics card.
Would something like the
Process Explorer be able to help figure out the problem?
