Spain

### Provide a description that is worded well enough to be understood

Similar to some other allowed websites, mitele is also having an issue (not able to test entire site selection of TV shows) with downloading a TV show. it is geo restricted but user is in Spain. the error follows:
_Failed to parse JSON (caused by JSONDecodeError('Extra data in \'d":false}}</script> \': line 1 column 9378 (char 9377)'));_

### Provide verbose output that clearly demonstrates the problem

- [X] Run **your** yt-dlp command with **-vU** flag added (`yt-dlp -vU <your command line>`)
- [ ] If using API, add `'verbose': True` to `YoutubeDL` params instead
- [X] Copy the WHOLE output (starting with `[debug] Command-line config`) and insert it below
