BUG in StreamFab 7.x
In the latest version of StreamFab, when selecting .mkv as the output format, the downloaded episodes are still saved as .mp4 files.
The files are not assigned the correct file extension. Regardless of whether .mp4 or .mkv is selected as the output format, the final files are always saved in .mp4 format.
Additionally, the episode duration is not displayed correctly until I manually rename the file to .mkv.
