Couldn't logon mediaportal FTP so I put the file
here.
It was the only program with dvb subs present when tested subs so can't yet tell if some other show would actually work on my system. One note though, in that recording there are two dvb subs present, could that confuse the filter?
In other dvb-softwares which support subtitles you can select subtitle language, I think we need a feature like that on MP too. Better yet, give it an option to select primary language and secondary so if first preferred isn't available, display second preferred and if it isn't defined on ts-stream, just display subs that's in it.
