I think you hit the nail on the head (I use Roku). There is something that Disney is doing that exacerbates the latency problems with satellite communication that Netflix doesn't do. Changing Disney to SD does not correct the problem. Occassionally you will be able to watch a Disney show without the buffering problem, but for me, the buffering problem happens at least 50% of the time. Once it starts, you might as well head over to Netflix. There may be other issues, like time of day and weather, that affect all streaming services but that doesn't account for the discrepancy between Netflix (good) and Disney (poor). I may try looking into downloading entire disney shows during "free" time, but not sure how I will view them on my TV
