Added frame rate conversion to arbitrary frame rates.
Added logging to report non-fatal warnings during operations.
MPEG parser detects and reports timestamp discontinuities.
Added limited error concealment capabilities to input handlers.
Optimized audio filters a bit and added tap count control for lowpass, highpass, and resampling filters.
Added "new rate" audio filter to relabel an audio stream with a new sampling rate without resampling.
Incomplete audio format headers that are rejected by ACM MP3 codecs are automatically fixed with the required fields (the infamous "tag 0055" problem).
Added workaround for AVI1 files with MP3 audio being detected as MP3 files by Windows Media Player 8.

features removed

Fixed crash when job queue could not be flushed to disk.
VDFs that contained multiple filters were only showing the last filter in the library (regression in 1.5 series).

Fixed internal error when attempting to start an incomplete audio filter graph (unconnected pins).
Fixed garbage wLanguage/wPriority values being written to audio AVI track headers when converting an MPEG-1 file.
Fixed crash when attempting to load an AVI stream with an invalid sample rate (zero or infinite). Added code to guess and substitute a reasonable value.
