Hey everyone. I looked through the FAQ and searched the forums but was unable to find an answer for this. Hopefully someone can help out.
When I go to edit the extended tags of an MP4 file I am able to select TVEPISODE, TVEPISODEID, TVSEASON and TVNETWORK. However, I am unable to see a choice for TVSHOW. According to the tag mappings list (Tag Field Mappings – Mp3tag Documentation) I should be able to edit TVSHOW and TVSHOWSORT.
Although in "Mp3tag\help\main_tags.html" tag-field names for MP4 have been declared as available and supported, some tag-field names are missing in the picklist of the editfield "Field" in the dialog "Extended Tags...".
Once you have typed into the editfield the string "TVSHOW" and a value has been entered too, ...
and the edit dialog has been closed by "OK", then the picklist got the new entry "TVSHOW".
You should check, whether this tag-field TVSHOW (tvsh) can be read by other applications too.
