DGDecNV build 244:
* General re-factoring of the MKV support for robustness and
future maintenance.
* Fixed GOP stepping for MKV.
* Remove need for mkvextract for chapter extraction. It is now
implemented internally.
* Fix MKV audio delay reporting.
* MKV header compression support added to DGDecode.
* Fixed missing QP file for MKV demux.
* Support UTF-8 in the Demux menu.
* Implement the IDR_PIC_ID_WORKAROUND for all container types
and ES. This workaround fixes cases of AVC that have successive
IDR pics with the same ID. That is formally illegal but occurs
often in the wild. Previously, this workaround was enabled only
for MKV AVC streams.
* Adjust the times in the QP file when 'skip first' is enabled.
* Chapter and QP items that are contained in skipped M2TS files
are no longer included in the chapter and QP files.
* Doubled the application stack size in DGIndexNV.
* Fixed GOP stepping and crashes for some MP4 streams.
* Fixed autocrop bug for MOD16.
* Draw chapter marks on the timeline for bluray disks and MKV.
Use click-and-drag for precise positioning with bluray disks.
* The DGI file format is bumped to NV24.
