ok, im not an idiot but i really cant figure out what is going on when i author a dvd. Let me start from the beginning. I have one single MPEG-2 file. The file is in every single aspect that a dvd file should be in. When i open TMPGEnc DVD author, and open the mpeg 2 file in there. I then click author and it take about 10 minutes because the file is in perfect dvd condition. But when i go to test the file in power dvd before burning it to dvd, the audio is not alligned with the video. I have not had success no matter how much research i do on the problem. I just dont get it. Could some one please help me solve this problem? Thanks alot to the people that respond. Tim
