    Win XP Won't detect DVD videos

    Hi...

    I just upgraded my system from a Via KT400 chipset to a nForce4. It was a real pain getting the drivers installed, and when I did my old DVD - a LiteOn SOHW1633S - wouldn't detect any DVDs at all, video or data.
    In the end I replaced it with a newer version - the LiteOn SM16SP6S. Now everything works - except DVD video. It won't detect any region-encoded disks at all. It will read and play discs that have no region set, but will not even read data of a Region 2, which is where I live.
    If I try setting the region through control panel->system->hardware it errors and tells me to make sure a region 2 DVD is in the drive. Any ideas? I'm using Windows XP Home with SP2, a SATA Maxtor 250gb hdd, and I have a DVD codec installed.
    Is the region setting the problem here? Would that stop the system reading the disc as data at least? And how can I set a region if Windows won't do it ?

      The first time I use a drive, I stick a factory movie in and try to play with powerdvd, then the region selector does it's thing unless I flash the drive first with regionfree firmware.
      Let's narrow down the problem, tried a new cable? jumpers right on the dvd
      burner? does device manager and my computer see the drive? does it see cd's?
      nforce drivers are a PITA, I usually let windows sp2 be default then only add
      what sp2 doesn't have(looking in device manager) driver disks that come with mobo make good coasters usually.

          Like I said, the drive behaves great cept for video DVDs. Everything checks out, and yep - cables changed too. I can even burn a DVD movie and play it, from a DVD-shrnk copy of one I made before the change. It will read factory DVDs that aren't region-coded - cheap copies of old flicks and so on.
          What has me confused is that most factory movies it pretends aren't there at all - if I click on the drive it tries for a minute or two, and the mouse pointer briefly flashes a disk icon a couple times - but it won't read at all.
          Since the new drive also handles DVD-ram, after a while it puts up a blank window with the drive letter in the address-bar.
          So it seemed to me that either it wasn't reading double layer discs correctly ( >4.7gb) or there is a region issue. Since it happily reads an 8gb magazine DVD, I assume that isn't the cause. Which leaves the region setting, currently at unselected.

              When you installed drivers, probably you installed also nvidia IDE drivers. There are know to give many problems with burners.

              First of all check if DMA is enabled

              If this don't solve, try to uninstall them (only IDE drivers, both on primary and secondary), and restart windows to let it to install standard microsoft ones. This should solve
