I just grabbed a Vizio P65 and I am loving every bit of it so far but the Google Cast feature. Sometimes it won't let me connect when using Ethernet and I need to power cycle the TV. Eventually it will find the TV over Cast and connect.
My next issue When I attempt to cast from the app directly after a few minutes I get a notification that indicates an error has occurred and that I should try again later. This happens only when casting directly from the app. If I cast from the tablet it works great, but I get a lower frame rate and things tend to jitter just a bit when things get moving fast (cars, running, etc). This happens when using a Chromecast as well and I have just written off as status quo. I don't have this issue with any other apps like Netflix and Youtube, casting works flawlessly. Sadly, we use a lot of Hulu and this is really killing us. Watching James Franco stutter around in 11.22.63 is disgusting to the eyes, and knowing that the app has none of these issues but drops every few minutes is just maddening. Has anyone else had these specific issues?
