I have a Roku 2 (about a year old..Sling promotion) ethernet connected, hit about 90Mbps down. DirectvNow wants to buffer a lot (I know they've had their issues) but it also resets a lot, I can push the home button, screen appears, but app sound continues, uninstalled app, Roku is up to date. Tried wirelessly and it's all about the same. Is my Roku 2 dying? Can't find much online help..(tried Google). Any thoughts? Thanks. Andy
