I have an older Panasonic Blu-Ray player that I've been using for streaming for a while now. My frustrations are as follows:
1) From turning on the Blu-Ray player until starting the video I want takes about 1:30. There's a lot of steps to navigate. And a connection test every time I start/pause a program that takes over 10 seconds to complete.
2) The player will interrupt programming to tell me that the bandwidth is too low to continue streaming at the current quality.
3) Sometimes, the player will refuse to connect to Amazon to play a stream, even when I can stream it on my computer.
4) The video will frequently only play with 4 bars instead of 5 (5 is HD).
I have 10Mbps Fiber-based Internet, with a provider that actually gives me a little more. I use a hard-wired connection to the router, but I could do 50+Mbps Wi-Fi as well (that's box to router speed, not box to Internet speed.)
Would a Roku 3 help/fix any of the above issues, or will my experience be similar?
