    Standard madVR - high quality video renderer (GPU assisted)

    http://madshi.net/madVR.zip

    Code:
    madVR v0.12
    
    * rewrite of about 75% of the code
    * loads of bug fixes
    * improvements for DVD playback (macrovision complaints etc)
    * improvements for frame stepping during paused playback
    * re-added rendering stats to OSD
    features:

    - high quality chroma upsampling
    - high quality scaling (bicubic, mitchell, lanczos, spline etc)
    - high quality YCbCr -> RGB conversion
    - gamut & gamma correction for display calibration
    - full 16bit processing queue
    - final 16bit processing result is dithered down to RGB output bitdepth
    - bypasses graphics card's video (damage) algorithms
    - all work is done via GPU shaders
    - no shortcuts, highest quality has priority over anything else

    requirements:

    - graphics card with full Direct3D9 hardware support
    - at least 128MB of dedicated graphics card memory
    - Windows XP or newer

    disadvantages:

    - hardware accelerated video decoding (DXVA) is currently not supported
    - slightly slower startup when using 3dlut technology (96MB file must be read)[/QUOTE]

    Standard AW: madVR - high quality video renderer (GPU assisted)

    http://madshi.net/madVR.zip

    Code:
    v0.4
    * modified (improved?) initialization order
    * fixed: aspect ratio was incorrect with some sources
    * added Lanczos8 resampling option (but I don't recommend to use it)
    * changed the way the GPU textures are updated
    
    v0.3
    * lowered CPU consumption a bit
    * playback start is now delayed until 3dlut file is fully loaded
    * during initialization madVR posts a message to the screen
    * added OSD (on screen display) with some stats, can be toggled with Ctrl+J
    * added display refresh rate detection
    * added GPU rendering time measurements
    * Direct3D resources are completely freed on exit now
    * errors are now properly handled and displayed
    * if 10bit textures are not available, 8bit textures are used instead
    * fixed: window size in GraphEdit was slightly too small
    * missing 3dlut files are now automatically created by calling "cr3dlut"
    * depending on source resolution "SD.3dlut" or "HD.3dlut" is loaded now
    * renamed "madVideoRenderer" to "madVR" everywhere
    * settings are now saved to (and read from) "settings.ini" file
    * improvement for playing video on secondary monitor (not tested)

    Standard AW: madVR - high quality video renderer (GPU assisted)

    Code:
    madVR v0.9
    
    * bigger part of initialization is done before playback is allowed to start
    * if Direct3D device is lost and can't be recovered, playback is paused
    * if paused playback is restarted, madVR tries to recover lost device again
    * decoders are now forced to deliver video width which is devidable by 16
    * reduced CPU consumption a bit
    * changed video -> GPU uploading method -> lower GPU rendering times (?)
    * OSD lists texture uploading times again
    * OSD now only increases CPU consumption in detailed mode (2x Ctrl+J)
    * external shader*.dat files are gone, compiler 41 is now always used
    * when final VSync estimate if off a lot, a file "vsync.dat" is created
    * fixed: 3dlut colors were ever so slightly incorrect
    * fixed: shader math colors were slightly incorrect
    Who is General Failure and why is he reading my hard drive?

    He was trying to get in touch with Private Data but if it involves a Major Disaster I understand that the fault lies with General Protection.

    Furthermore, if you cannot reboot it may be because of a corrupt Colonel.
