Hello everybody!

I\'m new here, so I\'m not quite sure in which section to post my question. I would really appreciate it if someone could help me.

My problem is as follows: I have two parts of a movie that both consist of three vob-files. I\'ll call them a and b. I join the vob-files using Vobedit. Then I create new ifo-files using Ifoedit. Finally I burn the a-b combination on a dvd using Nero. When I watch the dvd on my player,  the following happens. When the movie ends, it starts all over again somewhere in the middle. The movie should be 50 minutes long, but somehow it starts again and lasts 80 minutes altogether. When I try to fit this movie with another movie on one dvd with DVDShrink, it says that Title 1 is 80 minutes long, when it should only be 50 minutes.

Have you heard about this kind of problem before? I wonder what I am doing wrong. I\'ve been searching on the net for hours, please help me!
