Can't Play Music CDs or DVDs

[DarrellS]

I burned a DVD yesterday with TDA and when I put it back in my Liteon 812S Combo Drive, I got this error message...

Access to the specified device, path, or file is denied

I put the DVD in my Philips 642 and it played flawlessly, all the way through.

I decided to try a music CD and I got the same message. Every single music CD or DVD that I've burned gives me the same message.

I can open the files in Windows Explorer and play the VOB and CDA files in PowerDVD but the audio CDs have trouble with about the first 15 or 20 seconds of the Music CDs and I can't hear any sound from the CDA files if played in any other player (WMP, MMJB CDPlayer...). None of the disks will autoplay and all give the Access denied message.

I installed an ATI driver update from the Windows Update site the other day which allowed ATI to highjack all my file associations and I thought I had them straightened out but obviously, I have alot more problems than I thought.

I am running Windows 2000 Pro. The non-user-friendly OS.

Well, I spent all day yesterday trying to reinstall Windows 2000 but kept getting error message after error message about the drive being corrupted or damaged. The operating system seemed to be installed but the Liteon drive would only work on certain CDs. It would install one program but tell me there was no disk in the drive on the next.
Also, every time I would restart the computer, I would receive a message...
PXE-E61: Media Test Failure, check cable
PXE-MOF: Exiting PXE ROM

Not having a clue whether it was the Liteon drive or the WD Hard Drive, I decided to buy both a new DVD combo drive and another hard drive.
Well I have most everything reinstalled and although everything seems to be OK, I'm still getting the Media Test Failure error (don't have a clue what it is) and now I have to enter a password everytime I restart the computer which I didn't have to do before and I did everything I could think of to keep from having to do it since I can't stand all this security crap with NT systems that make you jump through hoops to use an operating system that you payed for on your own computer.
