@BostonDriver If your Roku is an Ultra, it's 4K. The very first 4K capable player was the Roku 4 (model 4400), which was released in Oct 2015. Long time ago. The first Ultra (4640) came a year later, but it supports 4K and HDR.
Some of the menu options he mentioned are only available once you have selected a title. I just tried it on one of my playlists. I selected the first movie in the list, which opens the window with the movie information and the play button. When I press the * button within that window, there are three options: Shuffle, Repeat All and Playlist Mode. I have no clue what the last one means, but for the other two it's pretty obvious. I had forgotten about this particular menu, as I build my playlists in the order I want them played. but you can enable shuffling the contents of the playlist, and with the second options you can have it start over once it's played everything on the playlist.
Note, I went into my main title selection, and once I selected a title the same three options are available. So it doesn't have to be a playlist to have the shuffle function. I even tried it on a USB stick which has seven different test clips. I can select one video, and the * menu still offers the same three options.
