  2. A typical DVD drive has a CD laser diode and a DVD laser diode. It could be that the latter is malfunctioning.

    Here is a reference circuit diagram for a cheap DVD player:

    See the pinout of the HITACHI 1200W optical pickup unit on page 3. Notice the separate pins for LD(DVD) and LD(CD).

  3. Ok, thanks xD

    I agree to fzabkar, There are two Lazer Diode each for reading CD and DVD. The Lazer diode which reads DVD is either weak or not working. Send it to service center or call Computer Technician to get it repaired.


    Would be cheaper to just buy a new drive than pay to get it replaced.

  5. Replacing the drive would be much cheaper than repairing it. In any case, I doubt that you will be able to find a replacement optical pickup unit.

  6. I have the same problem....but it might be to my own ignorance.....I bought a used/wiped XP desktop......it will not run DVDs.....I downloaded VLC Media Player, after realizing, doh, being wiped, maybe it needs something to allow it to read DVDs. But, even after reboot, it still doesn't work. In Win Explorer, the DVD drive still shows no contents.

    I did a ton of reading, prior to realizing I might need a decoder, thinking maybe I need a new drive. But, don't want to go that route, until I'm sure.

    What do I need to do, for this back to defaults, XP computer to get the DVD drive to read DVDs?


    Thanks in advance.

  7. If Explorer is able to display the contents of a data CD but not a data DVD, then the optical pickup is probably faulty. The pickup has two lasers, one for reading CDs, and the other for DVDs. Their wavelengths are different.

  8. On, in the case of an old machine, might that be a CD drive?

    I would've replied sooner, as I have mail notification enabled, but I got no emails of replies.....

    Anyhow, I read in some places about the separate lasers for CDs vs DVDs, so know that's a possibility. But, if a computer is not "new" from a store, etc, is there not something you need to add to play DVDs?

    I'm somewhat skeptical of it being the drive, because I bought two XP desktops off Ebay, and neither one plays DVDs in the DVD/CD combo drive. Too coincidental for me. They both play CDs in these drives fine. DVD's do nothing and show no contents in Explorer.

  10. AIUI, data DVDs should show up in Explorer, but video DVDs won't play until you install appropriate application software plus the required audio/video codecs.

    In fact I have a newly built bare bones Win98SE system with a DVD writer as its only optical drive. I have installed no additional multimedia related application software. If I open Explorer, I see a video DVD containing AUDIO_TS and VIDEO_TS directories. The latter contains VOB, BUP, and IFO files.

  11. Ok....and these are game DVDs..so I am guessing not data DVDs...Titan Quest was the main one I tried to install. Star Wars Battlefront the other. Would not play on either.

    I downloaded and installed VLC Media Player.....should that not take care of the codec? From what I read it should have. Maybe I'm just missing something? I did that and it still didn't work. Or do I still need some sort of drivers/dvd software? I know they come resident with new computers, but what do we do with these wiped ones?

  12. Game DVDs are just software/data DVDs. They should contain a file system that is recognisable by Windows.

    In Explorer, if you can see the file system on a CD but not on a DVD, then AFAICS there must a physical problem with the drive.

    R-click the drive's icon and select Explore. If you can see a file system, then perhaps you have some peculiar autorun issue. You could also check the Properties of the disc.

    Other than that, I have no more ideas.

    I hear you there, but if it was just this one used XP computer, I'd buy in....but not when I buy two of them, from separate Ebay sellers, both wiped with Windows reinstalled, and neither reads DVDs. I'm still holding out hope there is something else I can do. I don't buy that both drives on both computers are bad.

  14. All I can suggest is to create a bootable USB drive with some flavour of DOS that includes a driver for your optical drive. Then try to perform a DIR on the DVD. That should eliminate any Windows issues.

  16. Here I am again on this topic...been over 2 years, but still can't play DVDs on this desktop. I hate computer hassles so much, I give it some effort, then I just move on and live life. But, wanted to run a DVD, so here I am again.

    I even found a Microsoft fix page that led me to edit the Registry, which I did. First it had me look for the aforementioned "upper and lower filters". I had neither. Then, it had me add a registry subkey...which I did.....sigh....still no dice.

    Any ideas? This is pretty ridiculous. Still reads no DVDs...reads CDs fine.

    I'm in the same situation as you. Maybe for another reason rhough, but give a try to the following (if you can), I'll explain further down :
  18. Try your DVD reader/burner on another system which you know is playing DVD flawlessly.

    I'm dealing with the same situation only reverse my... DVD player will play in the DVD's whereas it will not see CDs it won't recognize the CD is in there at all.
    and this is my second DVD player that I installed in the same thing is happening so I know its not the player itself it's something in the software or maybe permissions I don't know.,???

  • Hi all,
    I am going to add on to this thread because I am experiencing the same problem. The device reads and opens CDs and CD-ROMs but if I place a DVD or DVD-ROM in it doesn't read it.

    I have a Samsung Chronos 700z model bought in 2012. Windows 7.
    Matshita DVD RW UJ8A7AS

    In the past (after installing DVD decoder programs and ANY DVD) the computer wouldn't even recognize the dvd drive. I solved that problem with help from this forum by first uninstalling the dvd software I had installed including ANY DVD and then fixing the registry edit upper and lower filters.

    The DVD driver was playing fine until a week ago when it stopped reading some DVDs but not all, and now it won't read any of them at all.

    I have tried the registry and no upper and lower filters.
    Here is what it says:
    Default REG_SZ DVD/CD ROM drives
    Class REG_SZ CDROM
    ClassDesc REG_SZ @%SystemRoot%\System32\StorProp.dll,-17001
    EnumPropPages REG_SZ storprop.dll,DvdPropPageProvider
    IconPath REG_MULTI_SZ @%SystemRoot%\System32\imagers.dll, -30
    Installer32 REG_SZ storprop.dll,DVDClassInstaller
    NoInstallClass REG_SZ 1
    SilentInstall REG_SZ 1

    Virus scans did not find anything.
    I have tried uninstalling the Matshita from the Device Manager and on restart it automatically reinstalls.
    The Device Manager reports that the device is working properly. It identifies the matshita but sees it as just a standard cd-rom drive. Is this normal?
    The driver file is
    C:\Windows\system32\DRIVERS\cdrom.sys
    Provider: Microsoft Corp
    File version: 6.1.7600.16385 (win7_rtm090713-1255)

    I have also cleaned the drive with a cleaner.

    Can anyone out there help me?

    I went through all this with my XP PRO installation and finally just moved on to Free Easy CD DVD Burner and it solved all my problems with reading and writing to any CD DVD. I have no connection to koyotesoft so I'm unbiased. Maybe Windows just can't be fixed. I tried all their wizards, etc...nothing but changing to another program was permanent and hassle free. Give it a try, please! Dave

  • well well well. thanks orgwood. I did not download koyotesoft but went with vlc media player instead and it kind of fixed my problem. a couple of dvds actually played and i was also starting to have cd-rw disc problems, but that worked to and I was able to burn a cd. thank you. perhaps i will try koyotesoft after all since it may help to read all my dvds (although I think part of that problem was the age/condition of the dvds).
    thank you thank you

    You're welcome...I use VLC also but mainly as a media player, not a burner. For that I do use Free Easy CD DVD Burner.

    Good luck, Dave

  • It seems that there is some confusion in this entire topic. A DVD Video disc IS a data disc and there will be 2 folders visible when the disc is viewed in explorer. You don't need codecs or a media player to view these folders or even a burning program. If you click on the drive in explorer and you get the message that there is no disc in the drive, then it isn't reading it

  • After hours of searching I finally found a fix for my DVD problem on my Windows 7 system. The symptoms were that although my DVD drive could read CDs and data DVD-R disks it could not read data DVD+R disks or DVD movies. After trying several of the solutions posted around the net here is the one that worked for me:

    1) Right click on "Computer" in the Start Menu (or the on Desktop if you see it there)
    2) Click "Properties"
    3) Click "Device Manager"
    4) Expand DVD/CD-ROM drives
    5) Right-click the indented DVD drive that appears and click "Uninstall"
    6) Click "Action" in the main menu near the top of the window and select "Scan for hardware changes"

  • I realize that this is a old question. Interestingly I had the same problem in my laptop which I purchased recently in KL. I tried to play a DVD disc that was burnt in India. Fortunately the solution was simple in my case. Malaysia where I purchased the laptop comes under Group 3 country for DVDs. So the DVD drive was configured during manufacture to read the DVD made in the same region 3. The Laptop allows to change the region a limited number of times only. So in my case I changed from region 3 to region 5. I had to close the player and re-open it. Bingo! The windows media player is playing the DVD now!

    I have reproduced the region details of the DVDs below:

    Standard DVDs

    Region 1: U.S., U.S. Territories, Canada, and Bermuda
    Region 2: Japan, Europe, South Africa, and the Middle East, including Egypt
    Region 3: Southeast Asia, East Asia, including Hong Kong
    Region 4: Australia, New Zealand, Pacific Islands, Central America, South America, and the Caribbean
    Region 5: Eastern Europe, Baltic States, Russia, Central and South Asia, Indian subcontinent, Africa, North Korea, and Mongolia
    Region 6: China
