Since you got a new cable box, you will need to configure the Slingbox for it. You can do that under Settings>Configure Input. This article should be able to further explain.
To understand what is going on with the HDMI connection. take a look at this article. It will explain a few things you may be experiencing.
- Slingbox.com - Using an HDMI video source with the Slingbox 500
- Slingbox.com - I get no video with any SlingPlayer (Watch, Windows, or Mac OS)
Hope this helps
Thanks. I reviewed my settings and I had earlier reconfigured for the Motorola Box RNG150N. However, in case something had been missed I did a reset and reconfigured it again. I double checked the remotes and they all work. So I then opened my iPad app and I can change the channels at will with the remote icon (still the old version of Comcast). But prior to switching to X1, I was able to build Favorites on my Slingbox App and then simply touch the Favorite and the select Watch and the channel would change to the Favorite. Now I get confirmation of the selected favorite but i can't activate the Watch function on the Favorite. So that is not working on the remote app. I have experience do this with the previous Comcast version. So currently I need to do all selections by manual entry of the channel number. I wonder if I should delete the previous build of Favorites and rebuild them?
Ok Anthony. I presisted and reexamined my input settings. I guess I had Motorola RNG150N when I should have selected Comcast and not selected RGN150N but the Model X1. That did it and now I can select from my Favorites or Guide and the channels switch as they should. So the lesson is to be careful selecting the right cable box. I have both HDMI and Component cables connecting my Slingbox. I need to see if both are configured. I know I did both.
