M GO is very disappointing "The Downside
The only playback/performance issue I experienced with the Roku 4 involved M-GO's 4K content. I rented the 4K version of "How to Train Your Dragon" and tried to watch it at about 8:00 p.m. on a Wednesday night. Even though my network speed test revealed a 55-Mbps speed through my wired connection, the video kept freezing and quitting. When I adjusted the resolution down to 1080p, everything was fine, so I'm fairly certain it was a 4K bandwidth issue.
Throughout the next day, playback was hit or miss; sometimes it played smoothly, and sometimes it didn't, even though my network speed kept registering the same. When the movie played reliably, the picture quality was excellent--probably the best of all the 4K content I watched. Just be aware that quality like that can take its toll on your network. Technically, this is more of an M-GO issue than a Roku issue (I didn't have any problem with VUDU's 4K rentals); however, since the two have teamed up to feature M-GO content on the Home page, I think it's worth mentioning.
