I have to second this.
The TCL 3700 Roku TV has some issues with keeping a stable stream on most channels. I was able to stream a basketball game on CBS on Sunday afternoon and it worked pretty well. However, most cable channels, on demand, HBO, etc. would only work for about 5 minutes. Once it needed to rebuffer, it would not fully come back and the TV itself will start to freeze up.
I think there is cause for optimism given how well the broadcast channels seemed to work, however there are clearly streaming issues that need to be addressed through the Beta process. In its current iteration, its not really useable on that TV at this time.
I also have a streaming stick in another room and it appears to be working well with the app, so the issues I am experiencing seem to be localized to the TCL TV. The wireless connection appears to be "Good" in both cases.
