Hey im having a very frustrating problem when burning mpeg-2 files onto dvd’s, i use Xilisoft Video Converter to change my .AVI files to .Mpeg2 then i use InterVideo WinDVD Creator 3 to burn it to a dvd… but when its all done my audio is like 5 seconds off of the video when i play it on a dvd player, the movie i made was Click and i put in a dvd menu into the start but im not sure if thats the problem,but i need to know where in between burning n playing on dvd player that it screws up, help would be greatly appreciated
