Advertisements In the last few weeks I've noticed on my TIVO Roamio some weird, movement streaking happening. Basically like lines along the edges of person showing if they move quickly. It's not constant, but it's bothersome. I suppose it could be the Comcast signal, but I'm not sure. I've got an older Roamio with a cable card via Comcast setup, original hard drive, with no changes to it. Ideas on this?
