Thank you for contacting Slingbox Forum. I am sorry you are not able to get the video remotely now.
You said you are using the HDMI cable and that is the root of your problem. Here is a link to assist you: When I connect my set-top box to my TV with HDMI connections, I can't stream video at all using any version of SlingPlayer. Why?. I think you will find this article very informative!
Hope this helps with your issue!
Have a great day!
