I tried to add an external ass subtitle when playing the main title in a BDMV folder. However, at the beginning of video, the subtitle was already about an hour ahead of the video. I tried to play the BDMV folder with the subtitle in Potplayer in Windows and there was no problem. It seems that infuse treats the subtitle for the whole Blu-ray rather than the selected title. As infuse automatically ignores some titles (e.g. titles showing Blu-ray menu and the copyright information) before the main title, the subtitle for the main title becomes way ahead. Can this problem be fixed?
