[bugs fixed]
* Improved accuracy of "set so audio and video durations match" for short
clips.
* Fixed vertical chroma positioning errors when converting to 4:2:0 or 4:1:0
YCbCr.
* PluginSDK: Direct stream copy from a plugin audio stream caused
dwStreamSize in the AVI to be set incorrectly.
* PluginSDK: Fixed crash when using plugin to load a file with an audio
stream that isn't AVI compatible.
* Capture: When "wait for OK" was enabled with a DirectShow driver, time
spent in the dialog was counted against a time stop condition.
* Capture: Fixed crash when an error occurs while starting capture with a
custom hotkey. 

[regressions fixed]
* "Save segmented AVI" no longer crashes when only video is enabled.
* Prohibit zero for frame rate adjustment.
* Filters: The error return from runProc is ignored again for compatibility
with earlier versions of VirtualDub; this fixes some video filters that
broke in the 1.7.x series.
* D3D: Fixed a display change related crash.
