You could use a different driver. the one I use is called XBCD (should show up in a google search). There has been several topics about this already so if you want more info you can do a search.

If you are using any 64-bit Windows then you will have to disable driver signature enforcement to be able to use XBCD which is an unsigned driver. (the simplest way is to just hit F8 on bootup and select "Disable driver signature enforcement" They can't afford the $100 per year license fee that MS requires for signed drivers. Rather than trying to come up with their own encryption they decided that it would be better to hire real cryptography experts and subcontracted Verisign to do it for them. Driver signatures are issued by Verisign not Microsoft and this is what the license fee is for. So far nobody has managed to actually break their driver signature and not for lack of trying.

As for the reason for all this, blame the RIAA and MPAA. They went to Microsoft and told them that they wanted Blu-Ray video decryption locked down on Windows (if you have driver signature enforcement disabled then Blu-Ray movies won't play) and hinted that if MS didn't comply they'd have legislation passed that would force them to do it. MS would rather do it voluntarily than have a law that forces them to do it in a probably much more restrictive way.
