Should be any Roku. It was added to an older Roku 2 HD I had through an update and was already on the list on my latest Roku 3 when I linked to my account. You may have to find TWCTV in the channel list or can add from the Roku website. /Dan
I had not realized those older Roku's even had existed so was originally thinking they all got the app. You were an early adopter. I guess I had a TV and BluRay that was new enough to have anything I needed for the last 3-4 years. The Roku 2 HD with TWCTV was first bought for an upstairs TV since no cable lines upstairs at the time.
