I have a .ts file that contains programs 3, 4, and 6. I need subtitles for program 4. I set the program number to 4 in "Obscure settings" and changed from "auto/default" to "ts" in "Basic settings"/input file format.
I get the error: parameter -inp=ts not understood
If I use "auto/default" for the input file format, the program number is ignored.
