I need help. I have been sucessful in burning DVD's from pre-authored DVD's, but all of a sudden it is not working. My steps are: 1) DVD shrink 2) Nero Burning ROM, click on DVD video, Far left click on Video_TS > add files, which is done and looks appropriate, then click on the Burn the current compulation, which it appears to do. When I go to play the DVD in either the DVD-R or DVD_RW drive it days "no media present". I know it's not a disc quality issue because it has been successful many times up to now. I am not doing multi-sessions so I don't think its a closure problem. What am I missing...I have wasted too mant disc's....HELP!
