Unable to play from Library

Just installed aTV Flash (2.6) and all appears to be working fine except one minor issue with Infuse.

I’ve a share to a HDD connected via USB to my Airport Extreme Timecapsule.

Drive shows up under My Files and they play fine. Added a Movies directory and TV Shows directory to Favourites and they play fine.

However, if I go to the Library everything appears fine until I select Play. I then get an error - ‘Playback error - an error occured loading the content.’

Any ideas what’s causing this?
