I am a new customer. When I select On Demand from the remote, the menu loads, however, upper-right quarter of the screen (that displays video previews, etc) is completely pixelated/blocky and the sound drops. This does not occur on my bedroom STB. I've ordered a few 30 minute On Demand items from the affected box and the pixelation does not seem to occur, though I fear something is clearly wrong if the menu video is messed up.
I've reseated and changed the coax from the wall to the STB in question with no results. I've also reseated all the connections at the splitter coming off the OTB. Anyone else ever experience this?
