I am new to DVD burning and without much success, but I have experienced Nero Express 18.104.22.168 freeze while burning .avi files to DVD. In this situation, Nero's "abort" function fails, and must be terminated with MS Task Manager. Nero never gives an error message.
I found my .avi files had video corruption (psychedelic colors on a B&W movie, or mere blocks of wrong colors) for 15-40 sequential frames. Nero apparently chokes on this sequence, while Windows Media Player plays on.
I am using a LITE-ON DVDRW SHW-160O6S burner. (2 weeks old)
Windows XP SP2 // AMD 2800 // 512 MB RAM.
Nero Express 22.214.171.124 (exclusively, for now.)
(for what its worth)
