Hi. It has been quite a while I've been tampering with different software trying to find a way to insert a THX vob trailer in my compilation before the movie starts. I downloaded trailers from http://www.cinenow.com/fr/vobtrailer.php3 and save them neatly in a file on my hard disk. I understand I need an IFO file to be able to burn them on DVD-R so I tried to create IFO with Ifoedit but didn't succeed. I incessantly got a message saying: no-navigation pack found in vob file(s) VOb may be invalid. What do I have to do. I'm desperate. It seems that I'm the only one trying to place a vob trailer before a movie on a DVD-R. Please help me. Bye.
