Actually, if you have DSL it might be your network in conjuction with the Roku box. On your other devices, the Netflix player does a slightly better job or stepping down the quality of the video coming from Netflix then the Netflix Channel on Roku. I've noticed my Roku HD doesn't do a great job of it. Now, my network is more robust than yours so it doesn't really affect me whereas with the slower DSL connection it may be that the Roku isn't stepping down adequately enough. The *real* issue is Netflix's (ill-advised) decision to switch from Flash to Silverlight technology a couple of years back... but that part is just my opinion.
You can complain all you like to them, but the bottom line is you probably either need to ditch the Roku or upgrade your Internet connection.
You would think... but NOT the case.... I can't even get the Instant Queue to show up on my Roku. It worked 5 weeks ago, perfectly fine. It worked for months before that, with a few times where it didn't work, but not enough to complain. This time it has been 5 weeks, nothing from Roku. This is TOTALLY a ROKU issue. 100% Roku problem.
I am tired of their lack of Customer Support ... I am tired of not being able to watch Netflix on it. I am tired of the crap Roku has been providing the last 5 weeks. I will NEVER
refer Roku to a friend. I will NEVE
R buy Roku again. I will complain until Roku refunds
