i keep my files as iso files so there easier to store and burn for me and so on. but i have one file that came as a mp4 and i converted it to a video file using super and the sound was off wen i played the video file. but the orginal was perfect? i thought it was just a mishap so i converted it to a avi as that is usually what my orginal files are and ive never had a problem from that. and the avi was fine no problems with sounds. and then i converted it to video file and iso not thinking to check it. and again the sound was off by close to 10 seconds. can someone help me please?
