When I boot up my computer and insert a commercial DVD, Windows Media Player tells me
"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."
There is only a workaround to this error, I have to run IE as admin and visit this site:
And perform a "Security Component Upgrade". I then reboot and the error has gone, Windows Media Player plays the disc normally.
However, the next time I try to play a DVD, (usually a few days later), the error will have come back, and I will have to go through the DRM upgrade procedure again before I can play the DVD. I've had to do this "upgrade" dozens and dozens of times, basically every single time I've wanted to play a DVD over the past year.
I'm using Windows 7 Home Premium, the latest version of Windows Media Player 12, and I have an Nvidia GTX 560 graphics card with the latest graphics drivers (currently Geforce 301.24). I have a Samsung SH-S223C 22x SATA DVD RW Writer Burner. However the problem has persisted through several different graphics driver versions and even over two different DVD drives.
I have enabled automatic updates for Windows Media Player but it has not helped.
My question is why does the error keep coming back again and again? Why doesn't the "Security Component Upgrade" last longer than a few days, or the next reboot? Does anyone know more about what the Security Component Upgrade process does, and why it would only be temporary?

First, I suggest you clear DRM cache, then try to upgrade Security Component Upgrade again.
Also, you may try the following possible solutions.
1. Disable Windows Media Player in Programs and featrues, then re-enable it.
2. Try to uninstall all the codecs, then install k-lite for a test.
3. Follow the steps in the KB to reset DRM

I spoke too soon, the problem has come back.
I downloaded the file from the link you give in step 3 and it played fine. I don't have a preinstalled version of Windows 7 anyway.
I'm not sure how to uninstall codecs. If Windows 7 is supposed to play DVDs, why can't it play them reliably? I think Microsoft should get their top man on this.

I didn't do that, as it says "The ResetDRM tool should only be used if all Windows Media DRM and Zune DRM content playback is nonfunctional." However, like I said, my computer played the test file, which "requires Windows DRM and Zune DRM to be fully functional in order to play."So the fact that my computer played the test file means that Windows DRM is fully functional, and it says I should use ResetDRM only if playback is nonfunctional. So I wasn't sure if it was a good idea to use it.
