I hate my Slingbox M1 and can't wait to sell it. Video quality is terrible despite high speed upload and download internet on both ends. I tried it with the port settings normal and with a dedicated port opening with no improvement. SlingPlayer app on PC refers to menus that don't exist within the app. Internet reset after a power outage and returned router to factory settings. Now the Slingbox won't allow me to do anything to reconnect it despite a soft reset, a hard reset and combing through support FAQ. What a F***** waste of money!
