Hi, I have an authored DVD (VOBs & IFOs) with 7 clips on it, all of which are unique chapters. 4 of them start to soon the in the video and I would like to adjust the IFOs so that they start a few seconds later. How can I do this? please provide all the details.

The same goes for the ending, any way of tweaking where the chapter ends?

I'm trying IFOEdit but I'm a little lost

Thanks alot!!
