Blu-ray home theater system

Why can't I change the "Audio Output" on my Philips Home Theater System? Why are the speakers grayed out in menu?

Why do I get the error “Status: Fail. Wireless Network is not found” when trying to connect my Philips TV to my wireless network?

What is VUDU ?

Where can I find my IP address, Default Gateway, Subnet Mask, and DNS Servers?

Why can I only see the Instant Queue in the Netflix app on my Philips TV, Blu Ray player or Home Theater system?

What internet features does my device have? Vudu, Netflix, Facebook, etc…
