...On my Roku TV, where I still have the MH series, I was going to check to see if it showed up on the Roku channel search, but my search isn't working, and doesn't show up, at all.
When you say "search isn't working" do you actually mean that, or that this particular show didn't return any results. Because those are two different things. What do you mean, "isn't working?" At all? No search returns anything? This may be indicative of some other issue, and may be important.
And in the top right corner it says press * for options, but that feature doesn't work either.
That always shows. What's key is if it's grayed out or in regular text. If grayed out, then no, it won't work. If it's not grayed out, then there's an issue. It's supposed to work. This, combined with what your answer is on "search isn't working" may indicate some other issue.
