Hello, i hope someone could help. When trying to open a video file with Mpeg-4 Modifier, it goes till 100%, and then drops out a message saying "This is not a valid MPEG-4 video (Startcode not found at begginning of frame)Codec: XVID". I've got the same message when tried to open files coded with DIVX3 and that was normal. But what to do when Media Player Classic shows me this file is XVID MPEG-4 Video?! Maybe someone knows how to solve this because bitstream is packed there and i need to unpack it in order to watch on standalone player. Thanks in advance!
