What is the error message you get?
Perhaps it's the blank disks you're using. What sort of blank media are you using? I haven't used it, but perhaps the "Smart Burn Media Check" utility will give you a clue --> http://www.liteonodd.com/en/service-support/download/cat_view/44-/54-
The download is a *.rar file, so if you don't already have a utility that can extract the files, download WinZip from the LiteOn page or get 7-zip
