Thank you for using our answers forum. I'm sorry that you did not previously get a reply. I would be more than happy to assist you! I understand you are using Internet Explorer. Do you know if you a running a 64-bit or 32-bit version of Internet explorer? Using a 64-bit browser can cause some issues when using the SlingPlayer plug-in. Below is an article that explains in more detail.
Hope this helps!

I'm using the 32-bit version of Internet Explorer and my OS is Windows 7 64-bit. I found another forum thread that said that the keyboard shortcuts for the remote control only work while in FULL SCREEN mode. I tested this myself and it appears that this is correct. Will the keyboard shortcuts for the remote ever work when you have SlingPlayer open in a window (not full screen)?
