    WMP9, PowerDVD 4.0.13C.2409, and SnapStream PVS 3.3 are installed on my
    P4/2.66 computer. PVS indicates that I have four MPEG video decoders

    1) InterVideo NonCSS Video Decoder for Hauppauge
    2) Ligos MPEG Video Decoder
    3) Elecard MPEG2 Video Decoder
    4) NVIDIA Video Decoder

    PVS indicates which decoder it uses for playback and allows me to choose a
    different decoder. I can't figure out which decoder PowerDVD and WMP9 are
    using. How can I determine which decoder WMP9 is using? How can I configure
    WMP9 to use a different decoder?

    Hi, Goto Start>>Run>>Type "DVDUPGRD /Detect" This should tell you the DVD
    Decoder WMP will be using. CyberLink (i.e PowerDVD) Decoder is "clvsd.cx"

    Thanks. DVDUPGRD /detect indicates that WMP is using IviVideo_Hauppauge.ax
    v4.5.28.92. How do I configure WMP to use one of my other decoders?

    I installed the nVidia video decoder just a couple of days ago--as part of
    NVDVD v2.27. Prior to that, a particular DVD played well in both WMP9 and
    PowerDVD. I used DVD X Copy to make a copy of this disc. DVD X Copy
    compressed the content in order to fit the copy on one disc. The resulting
    copy played very choppy in WMP9 and not at all in PowerDVD.

    Then I installed NVDVD. The copied disc now plays fine in WMP9; it also
    plays fine in the NVDVD DVD player. However, it still doesn't play in

    But now I have a new problem. When I play original DVDs in WMP9 or the NVDVD
    DVD player, the entire playback area is usually solid green. As I jump to
    different parts of the DVD, I'll see an occasional frame of video, but it
    immediately reverts to solid green. PowerDVD still plays these original DVDs

    Any suggestions on how to resolve this?

    I just upgraded NVDVD (including the nVidia video decoder) to the latest
    version--2.55. Now when I play original DVDs in the NVDVD DVD player, the
    discs play much better--only an occasional frame of solid green here or
    there. However, these same discs still play mostly solid green in WMP. They
    continue to play fine in PowerDVD.

    What could be causing this? DXDIAG seems to check out fine, BTW. DVDUPGRD
    /detect still indicates that it is using the Hauppauge decoder.

    I would suggest uninstall all of your MPEG-2 decoding software and install
    just one. Having more then one might be messing with WMP and Windows
    playing MPEG-2/DVD files in general

    Thanks, Chris; that sounds like a good idea. NVDVD has an uninstaller--which
    will likely remove the nVidia video decoder. But the other three decoders
    (InterVideo NonCSS Video Decoder for Hauppauge, Ligos MPEG Video Decoder,
    and Elecard MPEG2 Video Decoder) don't have an obvious uninstaller. How can
    I remove them?

    BTW, I also have the DivX Pro Codec installed; should I remove that, too?

    I have no idea how you would go about uninstalling all these third party
    codec's. Try contacting the makers of the codec's for "uninstall strings"
