Actually not enough "flashes" going on. I can live with pixelization for bulls games on comcast every few seconds. I can live with the slightest hint of bad weather shutting down my signal for sci-fi and a few other channels while rest chug along. I can live with searching for signal when I'm watching a recorded program. I can not live with 6 foot tall, hundred pound, hot accented mostly naked women who consistantly morph into less hot half naked women. Hd was made for married men to once a year watch and enjoy hd in all it's glory. It was like getting a lump of coal. Bah hum bug.
