Excellent app for streaming web-based videos to Roku3

I was looking for an app to stream live sports channel from a website that requires an Internet subscription (squashtv from psaworldtour.com). It works extremely well and is very simple. The video quality showing on my new Vizio M60-C3 4K TV doesnt appear to be full 1080p, it is better than using a video display cable from my MacBook Pro and once the video is playing on the Roku3, I can use the Roku3 remote to control the video (pause/rewind/etc)!
