Cast to TV doesnt work

I have many apps where I use the cast feature to my Vizio TV, but this is the only app that constantly has to buffer / load. Hulu works fine in my internet browser on my HTPC...the only constant is this app. Ill probably just cancel Hulu and stick with Netflix...which works with my setup.
