Additional information

The mp4 has a forced english track that plays in VLC (e.g. play at timestamp 36:24). FFmpeg also recognizes the track but ccextractor doesn't seem to be able to process it. Also included the tessdata 3 directory to convert the dvbsub into srt but it isn't recognizing the track so the OCR isn't working either.

Without tessdata directory
