WMA9 Pro and WMP6.4

    Its well known that WMP 6.4 has issues with certain WM9

    WMA9 (VBR)
    WMA9 Lossless
    WMV9 Screen
    WMV9 (Frame interpolation and interlacing)

    All those codecs/codec features dont work with WMP6.4 and
    some require WMP9Series to play. However certain third
    party players like Winamp and Media Player Classic can
    play them fine.
    So, my question is, does anyone know of any third
    party "hacks" or "patches" to make the above mentioned
    codecs work properly in WMP6.4? I really really hate WMP7
    and up. And prefer WMP6.4 above all else.

  2. I don't know of any. There is not much to "hack" around with in WMA 6.4

    What about this old message? http://www.tech-

    Would that apply to what I want?

    And, Why exactly does WMP6.4 have issues with WM9 anyway?

    Did you try the VCM wrapper mentioned in that message?

    Do you know enough C (not C++) to try to code a hack?

    WM codecs require the application to use some kind of
    certification when it tries to make them work and the
    certification model used by the v9 codecs (which should be
    "no certification") is incompatible with the way WMP6.4
    certificates itself. If you hack WMP6.4 to make the v9
    codecs work, you may break playback of some WMV files (in
    WMP6.4 only).

    Moreover, WMP6.4 uses the old WindowsMediaSourceFilter which
    is optimized for CBR network streams and thus it is very
    slow when seeking and does not provide a smooth playback of
    VBR local streams. If you hack WM6.4 to force the use of the
    newer WMASFReader filter, this one turns itself into the old
    WMSF (for compatibility, I suppose) and you gain nothing.
