Another version of the XBMC Mac derivative Plex has hit the airways. New features include Aperture support, new audio driver and thumnails for artists. The release notes found in the link below do a better job detailing the new and the improved.
NEW: James enhanced the Programs area of Plex.
Workflows can be added to the root-level menu, folders can be added as
sources, workflows can be selected by navigating into folders. (Plex
quits when starting workflows, releasing control of the Apple remote).
Additionally, you can run Applescript scripts from the Scripts menu, or
by mapping them directly to keys in the keymap files. This opens up
lots of possibilities!
