Please inform me of the minimum speed to watch History channel on the Roku TV without constant buffering. WE are in a very rural area with DSL that maxes out at 5 Mbps during non peak hours but drops to sometimes below 1 Mbps peak time. I know that 1 Mbps is not fast enough to stream History channel. But I often check the speed to find a time when it is fast enough so I can watch. Do you only stream in HD, or does History Channel stream in SD. Does History Channel measure the internet speed and adjust the Definition of the stream based upon the internet speed. If not, then perhaps you can update the system to do so. Otherwise I will have to stopp watching which I would rather not do as we enjoy a quite a few of the shows...It is our favorite streaming channel. Thank you for a response. Tim Hall
