I want to copy a dvd using files downloaded from programmes such as limeware etc. I have downloaded files which are AVI files. I have downloaded the programme Nero Vision 6, which has the Nero Vision Express 3 and other DVD burning programmes. All I want to know is what programmes I need to download to convert the AVI files into DVD files which Nero vision express 3 or other Nero programmes can use to burn to a dvd. I have tried burning the AVI files using Nero vision express 3 but the audio is out of sync when played back on a dvd player can someone tell me what programmes are needed to use to copy avi files to dvd.
