My Roku Premiere worked great since mid-May; however lately, many of the channels, especially the Spectrum channel are very low quality, pixelated, and show "Buffering..." often. I've rebooted the unit several times, checked the wireless network connection and it's fine (reset it twice as well), and checked with Spectrum Internet, and it's working normally as well. Anything else I can do, besides returning the unit and going with Amazon Fire TV??
