windows media player won't play certain drm files

[STFU]

It's about most video's on this site

http://www.rtl.nl/xl/gemist/

Recently they seem to have added drm to all their files, now I can still watch them in the browser, but I prefer to download them and watch them later. Downloading is no problem but when media player does the drm request it somehow doesn't connect. HTTP 405 error

I've tried it on XPsp3-WMP10 +XPsp3-WMP09 + VistaSP1-WMP11
I can play drm files here is a sample file

http://www.media-drm.com/Demo1.aspx

.

I also tried this.

Try this:

In Explorer make sure hidden and system files are viewable. Go to C:\documents and settings\all users\DRM. Rename the DRM folder to something else (such as "Backup DRM"). Reboot your computer. Go back into 4OD and when you sign in it should ask you to update the DRM software. Do the update and see if it works now.

When it ask to update the drm software with the sample file it works, but when i try the same procedure with one of the files from this website it gives an error.

Now am I wonder does anybody else have this problem and is it solvable.
This is an example to a link from this site :

for your convenience I also downloaded a sample from the website with drm.
