Oh boy…me from almost 2 years ago. So, now let me answer my own topical question:
None of the major players are produced with analog A/V ports anymore. The Express+ 3910 was the last player with them, and production of it was discontinued between the summer and fall of 2018, in favor of its successor model, the Premiere+ 3921. The 3910 is the only analog output-ready Roku model to be compatible with Voice Remote functionality and Apple AirPlay 2.
Now that should explain it.
I’m into videotapes and old electronics stuff, including extenders, converters and analog 4:3 TV sets (which are obsolete these days), and Miss Bianca is my favorite character in Disney’s The Rescuers (1977) and its sequel, The Rescuers Down Under (1990). I am not a Roku employee, only a user like you. ~ Jordan
