Roku Working Great this year
Just saying, watching the games on a Roku3 this year has been great. No stuttering or delays and no pause/catch-ups at all. It does take forever to build a buffer (probably because I'm on a 6/1 Mbps connection), but once the picture starts, it has been perfect. (Knock on wood.)
That said, last year the roku was un-useable for the first half of the season. I was forced to use my PC hooked up to the TV with an HDMI cable. Not that the PC doesn't work, but it is much easier with a Roku Remote which has a 10 sec skip back, or forward. And the schedule interface is great. And I don't have to jump hoops to log in, like the PC, apps. The Roku is always logged in. Just open the app and start watching.
What was Really annoying last year is that GCL forced us to upgrade to the Roku3, orphaning the Roku2. I didn't mind that so much, but I was not too happy when the Roku3 was not working properly.
My only issue, like others have said, is it would be nice to have something to watch besides an NHL logo between face-offs and periods. Generally, I wait until approximately the second period to start watching, and skip the breaks, so this issue is for watching live. Otherwise I could care less.
