There's also an OS X app ("DishWorld"), with which I'm having problems. I was able to launch it and log in, but I keep getting the same "allow incoming network requests?" dialog box, which is quickly followed by a "npMoveMediaPlayer unexpectedly quit" error, with "plug-in failed" visible in the player window (just like when you try to watch a Flash video with an expired version of Flash).
I've read that some people are having the same "allow incoming network requests?" error with the latest iTunes update, so I wonder if it relates to this week's Mac OS X update and not to the Sling TV app.
Anyone have any ideas? I probably won't use the OS X app much anyway, but it would be nice if it worked when I want to use it. Thanks.
