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.
