Variable names should be `in_pep8_style` instead of `inCamelCase`, in other words:
`episodeFolder` -> `episode_folder`
`deviceFolder` -> `device_folder`
`episodeArt` -> `episode_art`
...

Also, most of the comments are redundant, they just describe the action in English words. Feel free to add comments, but make them describe more than just what the code is saying, anyway.

For the camel case thing, see http://legacy.python.org/dev/peps/pep-0008/ as reference.
