Refactor ARD to run automatically in MIs gatherVideoInformation().
Since MI is not always executed when already run, ARD is also not spawned.
Fixed several internal things like forcefully gettin gmediaInfo et all...
check with a real DVD with multiple VOB files.
There might be still some chicken/egg mediainfo problem in getPositionInMediaFile()
Bluray UDF iso files do not work (DVD ones should work natively by FFMpeg)
We might need to integrate something like FFMpeg4J, which has stream reading...
