first off what format is your download..... if it's an ISO form all you need is ImageBurn to burn your DVD! If it's an AVI or MPEG format then you need to convert it to DVD Compliant files then burn..... you can do that with many programs but I use ConvertXToDVD and sometimes Nero! Here is a guide for Nero: http://forums.afterdawn.com/thread_view.cfm/272946 and here is ConvertXToDVD: http://www.afterdawn.com/guides/archive/vso_convertxtodvd_guide.cfm http://www.vso-software.fr/products/convert_x_to_dvd/
it could be your media! or your drive switched to PIO mode. check your DMA and follow this guide: http://my.afterdawn.com/alkohol/blog_entry.cfm/231/dmaissues use the good stuff.... [bold]Made in Japan[/bold] media is the best and prevents problems and errors! Always check the label on the box or spindle and make sure it says MIJ. the only Taiwan disk I would use is Verbatim, that's a top notch disk, too!
