What's new in this version:

[misc changes]

    * Inverse telecine has been disabled. It's not working nearly as well on various sources as I'd hoped, and so I've disabled it until I have time to fix it.

[features added: main program]

    * Direct support for YUY2 in both processing and capture modes.
    * VirtualDub can now detect when files are about to exceed available disk space and/or the 4Gb FAT32 limit, and close the file before the limit.
    * Replaced puny OS audio compression dialog with better, BIGGER one.

[features added: capture]

    * Capture: Implemented video clock adjustment in capture mode for better audio/video sync.
    * Capture: Fast field swap (RGB, YUY2, UYVY, YVYU).
    * Capture: Fast noise reduction (RGB8, RGB24, RGB32, YUY2, UYVY, YVYU). (Algorithm courtesy of Steven Don).
    * Capture: Fast 2:1 linear and cubic vertical reduction (RGB8, RGB24, RGB32, YUY2, UYVY, YVYU).
    * Capture: CPU usage detection works in Windows NT/2K.

[optimizations]

    * Added MMX IDCT routine to MPEG-1 and MJPEG decoding.
    * MJPEG decoding significantly faster.

[bug fixes: main program]

    * MJPEG mode selections no longer crash if the video isn't in MJPEG format.
    * Internal MJPEG decoder now handles output from PICVideo and recent Morgan MJPEG codecs.
    * Fixed video filter API causing filters to occasionally receive timestamps in us instead of ms.
    * Fixed MPEG-1 packet sync errors caused by improper handling of sequence end tags.
    * Fixed slight bias in MPEG-1 motion prediction.
    * Fixed MPEG-1 macroblock skipping at slice start [fixes KareKano op].
    * Fixed video compressor confusion when two codecs of the same format are installed under different FOURCCs (e.g. PICVideo and MainConcept).
    * Fixed intermittent file write corruption on NT/2K SMP systems.
    * Filters deinitialized on exit (thanks Joey Liaw).
    * Hitting Cancel on the audio compression dialog no longer disables audio compression.
    * Jobs with extended open options work.
    * Smoother filter saves noise prefilter option.
    * Fixed some miscellaneous "Unhandled Microsoft C++ Exception" crashes that were supposed to be errors.
    * Fixed audio segments getting dropped during preview whenever the pipeline stalled temporarily.
    * Fixed the stupid crash requester not saving crashinfo files.

[bug fixes: capture]

    * Fixed capture 'audio relative rate' value going negative.
    * Fixed not being able to disable 'stupid capture driver' settings in preferences.
    * Allocate disk space dialog properly shows current capture drive.
    * Disk space measurement works with UNC network paths.
    * Segments can now exceed 2Gb.
    * Fixed seek timing errors introduced in capture files with compressed audio.
    * No longer crashes when running out of spill drives.
    * Fixed crashing problems when using the 'save compression' option with [No compression] or codecs that are later removed.
