Thanks for your message! But just so you know, I support US products and customers. And from what I can tell, this model is for Samsung Latin America. (Correct me if I'm wrong.) So if you want the most accurate information, here's the Samsung Latin America portal for support on that product: http://www.samsung.com/latin_en/support/model/BD-F5500/ZX
Hope this helps you!
I was looking for BD-F5500/ZX firmware downgrade, is there a released firmware to do this?
My BDs firmware is BSP-F5500WWB-1003.0,
Main reason, having problems with DTS streaming, non compatible with my DTS decoder system.
