Bioshock and Nvidia Driver

Thanks for the help but unfortunately I only have 1 nv4_disp.dll in the folder :/

Use system restore to go back to a point where you did not have problems. Which would be my last resort before going to reinstall, you were quite thorough already. Also, did you make sure your directX was up to date.
EDIT: Some people claim lowering their hardware acceleration worked, bit of a bother but worth a try.

Different things to try in no particular order, probably none of them will work except possibly the last one:

If you got another video card, put it in there. Then switch back if the other card sucks. Put it in a different agp slot if you have more than one.

Find out if there's a setting attached to your user profile that's causing it. To do this, at your Winxp logon screen, press CTRL+ALT+DEL to bring up the login box, type "Administrator" as the user name, no password, and press enter. See if that user profile has the same problems.

Right-click on your desktop, go to Properties, and then Settings tab. Start changing everything, one thing at a time. Resolution, Colors, Refresh rate (use the List All Modes button), Hardware acceleration, write combining, all that stuff. See if anything behaves different.

If all else fails, it's time to re-install windows xp. I just re-did mine a few weeks ago due to hard disk problems, it's painful at first but it's over quickly enough and you'll have a peppy machine again.

I've fixed it!!!!

Praise the lord I didnt need a reformat. Took me 11 straight hours today to figure it out, but I can finally watch DVDs.

As you can see from the list I tried practically everything. I did multiple system restores (which seemed to duplicate that file 50 times) and tried some other things.

So I had searched for the driver I was using before Bioshock but could never find it (I did complete uninstall so I couldnt rollback the drivers). Well, it seems I had 1 number wrong in my search. Since 169.21 was the latest driver that broke everything, I looked for 169.18, which doesnt exist. The actual driver is 162.18!! So after I installed that one I can finally watch DVD's again.

This fiasco makes me kind of worried about updating my drivers, since 169.21 was recommended as a general upgrade for my card (169.28 was the Bioshock driver that screwed everything up in the first place).

So, probably nobody cares about this achievement but I'm telling you anyways! Thanks for all the help everyone gave me.
