I'm new to backing up my dvds and ive been using the guide on dvd2dvdr.com and instead of using prassi as my burning rom ive used nero 126.96.36.199. So i can successfully get an audio_ts and a video_ts file but when it comes time to burn, nero says "the drive is not getting ready! - perhaps due to bad media" and it wont allow me to write the dvd. can anyone help???
