I have no idea if this is related to EPG or not but I've seen issues over the last few years (?) with respect to looking up Actors and the movies they are in. As an example;
I go to My Recordings, add recording, search by actor name. I then punch in the actor name and often I will get no results. Here's an example I just noticed 5 minutes ago.
I looked up Daniel Craig and nothing came up. Nothing at all. (There are no items in this library yet...bla bla bla). But here's the thing, If I hit the back button and choose Daniel Dae Kim it pulls up all the movies he's been in. So I try out Daniel Cosgrove (whoever he is) and it pulls up his movies. So I go back to Daniel Craig and what do I get? Nothing.
I see this behavior fairly regularly. I assume Media Center is doing lookups over the Internet. This is why I chose two other actors, to see if it works for them, and it does. What's the issue then with Daniel Craig?
This always brings me back to, is EPG 123 now totally independent of Rovi/Microsoft? Ie, is it 100% using only SD ? Or are we still dependent on MS/Rovi for things? Is there what's causing the issue?
