i try to burn some dowload movie on dvd-r & dvd+rw with nero but no success.
Can somebody help me please
I think you posted a little bit insufficient problem description to make a statement about the reason. There is always a log file created by Nero if you try to burn something so you may either attache some snippets here or post it to Neros tech support.
Anyway this is NeroSDK forum so please use the correct thread.
