This is exactly what I think you need. I did the same thing and after two weeks of trying I ran accross this post. It worked pefectly :
-[edited-1/19/08]Another issue is not seeing your PS3(should be seen as "unknown device) in the “Media Share” window within Windows Media Player 11. What has caused this is not known to me. It may be because it was deleted in the Media Share window. But anyhow, there are three possible ways to fix it. The first way may be the best way....
This fix was found and edited by Hamah, and he and I confirm this as a successfull solution. I would highly recommend tring this first.

Check Event viewer and look for errors on the Windows Media Player Network Sharing Service
If you get the event error 14344 then you need to upgrade your DRM component. (I did not have these errors but followed this process anyway)
You can upgrade the DRM component here: http://drmlicense.one.microsoft.com/...en/indivit.asp
Though you must be using IE as your browser.
If you encounter DRM issues, cannot upgrade/update your DRM component, or see the grayed out 'Upgrade' buttons on the Security component upgrade page, it may be worth the while to check below link:
DRM Reset Utility - to download go and get this program here:
(I had to run this as the upgrade button was grayed out for me.)
Remember to restart your computer after running the utility.
Once you have restarted your PC go back to the DRM component upgrade site:
You should now be able to run the upgrade. Once the upgrade is complete check your 360 and your PC should be there."
