Hey,
I added a subtitle according to this guide:
https://www.videohelp.com/forum/viewtopic.php?t=219535

After finshing, I played the movie and it showed the logo in the beginning and after it just played a blank picture counting the seconeds.
In the original DVD after the logo comes the menu.
I can go manually (with PowerDVD) to the movie (through the GoTo menu) so I now the movie is ok.

My guess is this: when i ripped the movie with DVD Decrypter it ripped from VTS_01_1.VOB and not from VTS_01_0.VOB.
looking manually at VTS_01_0.VOB shows that the menu video is in that file.
I guess the IFO isnt linking correct.

I have added a subtitle in the past with that guide and every thing went fine, but in that time the menu was in a separate VTS. (I mean like in VTS_02_0.VOB and not VTS_01_0.VOB which also contains the movie)

I hope the post is understandable :\

I'll appreciate any help.
