    Windows Media Player does not conform to DNLA standard.

    Certain devices wll not play files of a certain type. e.g. Zensonic Z500

    Reference document "DLNA Home networked device interoperability guidelines
    (Part 1: Architecture and Protocols)" available here:

    According to "7.4.30 - MM DIDL-Lite protocolInfo values", any protocolInfo
    value that begins with "http-get" must list the MIME type and DLNA.ORG_PN
    parameters of the media format profile in the third and fourth parameters,

    In the case of WMS 11 for an AVI file, the fourth parameter (DLNA.ORG_PN) is

    Example: <res
    Should be: <res

    This is a bug in the implementation of the DLNA protocol in WMS 11.

    Applicable portion of section 7.4.30:
    The third field of a protocolInfo value must use the MIME types specified in
    Compendium of Media Format Profiles, Clause 5 in the Media Format document
    for DLNA normative media format profiles when the protocol is "http-get" or
    UPnP AV endpoints (devices and control points) must use the DLNA.ORG_PN
    parameter (7.4.32) in the 4th field of protocolInfo for the following
    * To identify content conforming to a DLNA media format profile, or
    * To specify that a UPnP device is capable of receiving, distributing, or
    content conforming to a DLNA media format profile.

    MIME-types in the 3rd field of [email protected] alone are not sufficient to
    identify DLNA content.

    MIME-types are not to be used to identify DLNA media format profiles because
    MIME-types will be updated by IANA.

  2. You should send this directly to Microsoft. This is not a managed newsgroup
    and MS does not monitor it for bug reports or feature requests.

    This is a fault in a Microsoft product that should be fixed forthwith. This
    is the only forum I could find to post it in. Indeed, this forum is intended
    to highlight problems with Microsoft products and request features. If enough
    people rate my post, Microsoft WILL look at it.

    In any case, there is no facility to report bugs to Microsoft. In fact, they
    would like you to pay to do it! Please go ahead and try. I will be very
    interested to hear how you get on.

    If you would care to follow your own link, you will find that there is NO
    facility to report bugs, unless you care to pay Technical Support. As before,
    I challenge you to find a way to do this, I would be overjoyed to hear how to
    do it.

    I will give it a try and report back, but I still think they will want me to
    pay to report it....

    Did you try it yourself? When I hit submit, after filling it all in, I got:

    Sorry, the page you requested is not available.

    Yeah, really good system they've got there.

    Please everyone, do not bother to try and tell me there is a way to report
    bugs to Microsoft, there just is not. I have now officially given up.

  9. Bug reporting for a released OS is not the same as it is for a beta. Bugs
    are reported to Product Support Services so that they can try to resolve the
    issue before escalating to the research team.
