I'm not sure if I've got the right forum for this question, but here goes. I have a series of wmv files that I want to convert to mpg and burn onto a DVD. Each clip that I want to burn to DVD is broken into 15 wmv files. I want to take all those wmv files and merge them together and then convert it to mpg so I can burn it as a single chapter on a DVD. I've tried converting the files to mpg and then merging the files into one.....however everytime I merge the files - the audio is out of sync with the video. I've also tried converting them to avi and I get the same results. I've also tried merging them into one file FIRST and then converting....but I get the same results. The audio starts out in sync with the video, but by the end of the merged file....the audio is out of sync with the video by at least 3 seconds...sometimes more. Is there a way I can merge all the individual files and then convert them to avi or mpg or convert them first and then merge them and still keep the audio in sync with the video? Can anyone suggest a program or solution to my problem?
