Do you mean add a different trailer for each episode of the series?? Yes, it can be done if each episode is a separate video file. The problem is to find trailers for TV series, there are very few available! Most TV series have only one trailer for the entire series. So, if you can find them, just name the trailer the same as the episode. The BBC has uploaded a lot of its episode trailers to YouTube : Upstart Crow (2016) s01e01 Star-Crossed Lovers.mkv Upstart Crow (2016) s01e01 Star-Crossed Lovers-trailer.mkv Upstart Crow (2016) s01e02 The Play's the Thing.mkv Upstart Crow (2016) s01e02 The Play's the Thing-trailer.mkv Upstart Crow (2016) s01e03 The Apparel Proclaims the Man.mkv Upstart Crow (2016) s01e03 The Apparel Proclaims the Man-trailer.mkv Upstart Crow (2016) s01e04 Love Is Not Love.mkv Upstart Crow (2016) s01e04 Love Is Not Love-trailer.mkv Upstart Crow (2016) s01e05 What Bloody Man Is That.mkv (No trailer found for Episode 5) Upstart Crow (2016) s01e06 The Quality of Mercy-trailer.mkv So when I click on the Trailers icon I get: Use the left and right buttons on the remote to move between episode trailers. Unfortunately I can't find a trailer for Episode 5 so there are only trailers for five of the six episodes available ! Remember to Re-match the series in HT when you've added the trailers! Don't use tvshow-trailer.mkv as in Kodi! They don't work in HT.
