This article is not all that helpful. The issue I'm experiencing seems to be what others have been describing as "rolling video." I've seen other a few other people post with this problem but no definite solutions.
I'll reiterate that i have determined this problem only occurs when the actual tv to which the cable box is hooked up is OFF. With the exception of the scrolling screen, the picture quality is very clear leading me to assume my Internet connection is fine. I'll also add that I have Comcast Xfinity in case that matters.
A few other users have suggested manually rolling back the firmware on the slingbox to the previous version. Before trying that I was hoping to get some official guidance from a moderator regarding whether or not that works. Or since this appears to be a semi common issue if there are any other definitive fixes.
