Sorry; you referred to the last time you did this, so I assumed you had looped multiple videos in Encore.
Easy to loop a video in Encore; just set its end point to itself. And you press menu to get out of the loop. But you want the remote control button push to move to the next video. The only button option you have is "next chapter."
I did a quick test, building to a folder and using TMT5 to test. I could not get out of the first loop without pressing "menu."
Anyone else got a clever idea?
