If I'm posting this in the wrong place then I'm truly sorry, I know there alot of similar post to this one but for some reason I couldn't post in those thread. I download a numerous youtub file and is trying to merge them together to burn on DVD but am having problem. I try to different software that people suggested such as virtualdub and mediajoint but there seem the be problem with the audio. The picture and the audio seem to be off, I check with the original version and everything is okay but when it come to the merge file the auto and the picture does't move well. Is there a way to fix this.
