When i attach a suitable subtitles on a movie in avi format and watch it on computer it is ok, but when i try to watch in on TV via USB the subtitle is being late. It is like, the first minute it is one second late the second two the fifth three the and so on it keeps being late . I download the movies from internet but that doesn't happen when i download them from some trusted uploader like axxo or fxg, then it is ok, but from someone like zeus_dias, vex or some unknown. How do i fix this problem?
