Over the past week, my Series 3 (the one with the LED front panel) has been experiencing pixelation issues on EVERY station. This applies to both recorded shows and live TV. Sometimes it is just annoying, other times it makes the shows unwatchable. I have replaced the hard drive a few years back so it isn't the original drive. I have another TiVo, a Premiere, attached to the same TV connected to the same splitter. I even tried switching the cables to see if it was a splitter issue, but the Premiere was fine while the S3 still had the problem. I checked the signal strength and all stations were above 90 even when I could see the pixelation occurring. Recordings from before the pixelation started play back fine. Any thoughts? Failing hard drive? Power supply?
