Well, I'll be damned. I was sure I checked that... I think I must have disabled it while I was trying to deal with the original issue.@smarty12345. As I suspected , the DVDArt plugin is not enabled on your setup. Go to MediaPortal Configuration and enable the plugin from the Plugins section.
Works like a charm now.
One more question.. In your DVDArt plugin, I notice it gets artwork for actors. But I cant see any option in streamedMP to view the actors details.. Is that a feature that for a different skin? or am I missing something else thats glaringly obvious?
