Changes:
Fixes since officical 1.5.10.1 release:

Cyrius:
- Fixed: (1.5.10.1) an input file containing audio would remain opened even
after "Clode video file" (thus preventing from deleting the file).
- Fixed: (1.5.10.1) crash when starting capture.
- Fixed: (1.5.10.1) ticks in the trackbar. Now have the same behaviour than
VirtualDub (when in "Frames" mode).
- Fixed: (1.5.10.1) not enough space was reserved for the KaxSeekHead at the
beginning of Matroska files. Added warnings (logs) when this happen.
- Fixed: duplicated references when writting 2 KaxSeekHead in Matroska files.
- Fixed: (1.5.10.1) logs shown 2 times when saving a Matroska file.
- Fixed: issues when decompressing AC3 (1.5.10.1) or audio using ACM.
- Fixed: issue with the input audio filter (graph) that would stuck the dubbing.
- Fixed: (1.5.10.1) problem with empty selection when doing a Refresh.
- Merged latest version of VirtualDub Sync by Andreas Dittrich (1.5.4, Sync 1.04)
- Fixed: livelock that could appear in some specific cases (the program encountered
a problem and is aborting the dubbing, but a livelock prevent it to properly end
the dubbing as well as showing you the error causing the problem).
- Fixed: issue when processing the very beginning of some AVI with MP3 VBR (this
problem would cause the previously fixed livelock).
- Added: 'Delete' key deletes entries in the stream, comment & chapter lists.
- Fixed: bug preventing some Matroska files from correctly being opened.
- Fixed: bug preventing files made with latest mkvmerge to be opened.
- Fixed: (Matroska) bug preventing processing of Matroska files (generally
resulting in a dubbing process stuck at the very beginning).
- Fixed: (stupid) bug concerning 'corrupted' data handling in DTS files.

Since last bugfix (build 2424):
- Fixed: (1.5.10.1) speed issue concerning dubbing thread priorities, and VBR
audio as input (e.g. VBR MP3 in AVI or as external source).
