How to use properly?

[alexanderadam]

Unfortunately I'm not a Go developer so I'm not quite sure whether I'm using it right nor am I able to understand properly what the code is doing.

Basic configuration

So I changed the remote programs URL to http://www.rtve.es/api/programas.json?size=%d&page=%d, because otherwise it wasn't able to find what I was looking for ({ "id": 83030, "name": "El Ministerio del Tiempo" }).
Was this correct?

Downloading

But even after this change it doesn't seem to download anything in my case:

Subtitles

Does it also download the subtitles?
If not: is it planned to integrate this as well (i.e. similar to this unmaintained script)?

For instance this episode has a vtt file that was linked in the subtitulos.json
