Cannot burn video, dvd or videocd in Nero

A friend of my is using Nero 6.6 (nero OEM 6.6.0.0 and NeroVisionExpress 2 21.216). But the problem as long as she use Nero she cant make (burn) any dvd, video cd (on dvd or normal cd both does not work). When se make a Audio , mp or/and data cd she has not got any problem.

When she start burning a dvd/videocd it seems to working but on the end she get an error that burning was not finished (or not good or something). She can save an error report she attach (watch here http://club.cdfreaks.com/showthread.php?t=224565).

Does somebody know what is wrong, does she need a file or what else.
Please help
