So i am cancelling my cable tv and going with a streaming service. i purchased a roku streaming stick. it works as advertised but the playback quality is terrible. ive tried changing the settings from 720 to 1080 but it doesnt help. Do any of you guys use this product or something similar? I have netflix on a tv already and the quality is better through the tv's netflix app than the roku stick. at this point im ready to return it and find another product but i dont know what to get. help please
