Issue with trickplay

[TheDreadPirate]

I am not seeing the error "Invalid quality value" error message anymore, but it appears that it isn't able to read files in "/data/tvshowsa". The "a" at the end isn't a typo. Can you double check the library path and permissions.

Code:

IMO, this looks like a permissions/invalid path issue since it affects pretty much everything in /data/tvshowsa.
