I recently Tried to play a DVD on my PC (Windows Vista Ultimate) and got this error message

Windows Media Player cannot play this DVD because there is a problem with digital copy protection between your DVD drive, decoder, and video card. Try installing an updated driver for your video card.

I have installed And reinstalled the latest Nvidia Drivers and also installed CCCP but im still stuck with the same problem. I did some googleing and found out that Vista Ultimate Comes with everything necessary to play DVD's

One last thing I had bought a External TV tuned a few weeks ago but every time i tried to play Live TV in Windows Media Center i would get sound but no picture and eventually i would get "Display driver Stopped Working" (almost the same symptoms As when i try and play a DVD) But in Dscaler live TV worked 100% fine? Could my DVD problem and Tv Tuner be having the same problem? (Shouldn't have taken it back so soon)

Anyways any help would be great.

This didnt help much, Windows Vista Ultimate Comes with all the proper Decoders and such for DVD playback, Im not willing to pay for a decoder.

Any other ideas?

MMMMM,have you checked under WMP 11 tools to see if ALL the file type box,s are checked?

Reinstall drivers.

Was this a burned CD/DVD?As in home made?
Or was this a shop bought?

How is WMP 11 setup not to play copy right DVD/CDs?
Or have you downloaded certificates for you to play copyrighted DVD/CDs?

Have you checked that the codecs are installed?
Have you checked your new tv tuner card is setup properly in BIOS?

Have you turned off onboard graphic card in BIOS?

Have you installed an encoder?

You need a payed for codecs as far as i can tell?

Update directx.

1. Where can i view these options

2. have reinstalled Video Drivers And DirectX multiple times.

3. Its a store bought DVD (Transformers) I have also tried many other DVD's

3. Idk? and no i havent.

4. as far as i know i have no Onboard Graphics. It was a External USB tuner and i took it back

5. I do not need a paid for codec. Windows Vista Ultimate Comes with everything you need to play DVD's

. I Because Microsoft-- or someone else says that Vista comes with everything needed-- does not necessarily make it so.

Video playback --especially copy-protected content-- is constantly changing.
You may need a codec- to make this video play correctly. You should not have to pay for it-- as there are people out there trying to keep up with every change they make.... but it may take a bit of trial and error for it to work correctly.
