I downloaded a .avi file and when I play it the audio is out of sync with the video. Is there any software I could use to fix this problem? I eventually would like to burn it to dvd. Thanks to all in advance for your help!!!
Try some of these solutions: http://www.gromkov.com/faq/faq2004-0064.html
though the versions of the software may be a little out of date since that article was published.
YAAI is up to 126.96.36.1995 now, and can be found here: http://yaai.sourceforge.net/
Converting to dvd is another task, and can be done with commercial programs like ConvertXtoDVD or free ones like DVDFlick.
