I'm trying to help a friend who is getting married in a few days. He has had a video of his courtship with his fiancee made; it is in MP4 format. He wants to put it on a CD, DVD or USB stick, connect it to his big screen TV, and have that video loop infinitely during the reception. I think he is trying to avoid having his laptop connected to the TV and leaving it unattended for several hours. Can anyone tell me how to make an MP4 autoloop if it is on CD, DVD or USB stick? It's very easy to make a video on a web page autoloop but I don't know how to do what he's asking. I'm GUESSING some little generic program like a batch file sits outside the MP4 file and points to it. When you start the generic program, you have a choice of which MP4 gets played (in case there several), then have a choice to play it once, a fixed number of times, or continuously. Or maybe the controls that dictate whether the file is played once, a fixed number of times or continuously is built-in to the authoring program for the MP4. However it's done, I'd appreciate some guidance on the best way to do this.
