Roku 3, direct wired not WiFi, Elite. I've had to reactivate while watching a program on PSVue at least twice. It doesn't ask to reactivate a lot thankfully but it is irritating and I don't have that problems with other applications.
Luckily it does not happen too often on my 3 Roku's. But every time I turn on Vue, I hold my breath. Once I see "Retrieving...." I know we are good. I just wish they could find a fix for this.
But there are no real alternatives in steaming, though ustvnow via kodi is pretty good.
Hopefully HULU live tv service coming out soon will put some pressure on Sony.
