Solved my problem but I hate what I needed to do.
I went to Slingbox.com and then I clicked on the little blue circle with a slash through it. I to remove ALL filtering and then website worked. I assume they did this on purpose so you cannot block ads in their player.
Anyway, the message they respond with sucks. It should say, remove all filters so we can run ads and track you so we can sell information to others. That would have been a better message.
Everything is working now. Not sure what changed the setting however.
