I am having a problem with my new Roamio Pro. When I Fast forward through a recorded show or use the 30-second skip, the screen will go black so I can't see the images on the screen to know when to stop fast forwarding. This happens about 50% of the time when I use either of these two features. Has anyone else experienced this? Is there a cure for this? Btw, I am still running the 20.4.1 level software if that might make a difference.
