De-multiplexing issue

[Noe]

I use TMPGENc to split the mpeg file into a video(mpv) and audio(mp3). After this the file is only about 5% of the full length of the videomusic file. I know the file is like 5 mintue long but it only split it and end up getting only 30 second of the audio and video. I know it is not because of the demo version because one of my file it fully split the the file and got the full length, but I realize that the videomusic with an intro has the problem.

Did anyone have the same problem? and is there a solution to this? I try searching but can't find no one with this problem. All I'm trying to do is get the full length audio file from the mpeg.

Try loading the original into Gold Wave and saving it there as a wave file or whatever you wish.
