I have an old Apple TV, that I think needs to be replaced. The only other two I know of is the Fire Stick and the Roku. Both have the voice control, and both connect via WIFI (my ATV connects using ethernet). I do have a question, and the answer might have a bearing on which one I choose. Can you FF and RV through recordings using the FS or the Roku, or both, or neither? Are there any other reasons to choose one over the other?
