I am trying to burn a DVD-R. I have used a Memorex 4x DVD-R and another generic brand, but it gives me error messages when I try to burn the DVD from Adobe Encore. Everything works fine when I use an older DVD-RW I have (a generic brand that I don't even know)and the drive works fine for other applications. I updated everything I could from the Pioneer download site, but I still can't make it work. Any other ideas? Are there particular media I should be using for this (particular brands, speeds)?
