My Bolt on Charter cable has been fine. But over the last few weeks, I'm getting some minor pixelation on HD channels. SD are fine. Charter now tells me they want to try tuner adapters. Note: This also happens on my XL4. Charter tells me that's all they can do. If that fails, the wife will have me back on Dish.... It's not bad... just reminds me of one of the reasons I left Dish. It was my understanding that the tuning devices were not needed. Any help or suggestions would be appreciated.
