I got this message after I burned a 8 gb dvd rom. After that I put a normal cd in the dvd drive and a message showed. The avi file was not prepared for sequential reading, the alternative "avi splitter" will now let the default one handle it. The complete reinterlearning of this file is strongly recommended before running it into a slow disc like cd rom. What does this message mean and should I be worried and if so what should I do to fix it, thanks.
