We just noticed something in the past week or so. With the digital set top box (the kind without DVR, no display, and you can see the Motorola CableCard through the top vents), the SD channels are getting clipped where bottom and top are being cut off (like ESPN crawl at the bottom). HD channels work fine. I tried cycling through the set up of the Panasonic Viera plasma we have for zoom, 4:3, full, etc. and even in 4:3 mode, the video is clipped. Anyone else seen this?
