Remuxing using VOB EDIT

Hello! Can anyone pleae let me know how you remux a full movie after it has been in REmpeg2? I used rempeg2 to shrink the file size down to 3.8gb and i've shrunk vobs 1 through to seven. I've seen a tutorial on how to shrink one single vob and place that back into a flie (think its darrow's). Can anyone help????:D Cheers

This link might be usefull: However if I do this I always loose the first part of the movie (+/- 1 minute of introduction) on a stand alone player. Someone has an idea why ?

Cheers, Of on hols for two weeks, will have a go when i get back, Chris.:D
