I have noticed that PlayOn Cloud auto downloads will fail if the movie title contains a forward slash.
Example from the log - Error downloading PlayOn #13553751 (The Naked Gun 2 1/2: The Smell of Fear): open /media/pi/Elements/DVR/PlayOn/Movies/The Naked Gun 2 1/2 The Smell of Fear (1991).mp4: no such file or directory
When I download the file directly from PlayOn the "/" and ":" are replaced with underscores in the filename. Example - "The Naked Gun 2 1_2_ The Smell of Fear.mp4". The date is removed for some reason as well when downloaded directly from PlayOn but that isn't all that important.
Is the "/" in "1/2" being interpreted as the start of a new directory and breaking the download?
