-it will set these attributes. If these are not available, it will check the second part. This means, it checks
-if german or english audio is available. It does not care for the subtitle, because it's "off", which means, it 
-will disable subtitles in this case.
+Subtitle lanes recognized as forced will be set as one. Already existing ones will not be overwritten or changed.
