Editing DVD video and audio files

[DPG Terik]

Ok guys, this may not be the forum to post this so let me know. Tyler may have posted how to do this at one time cause I think I read about it but I cant find it in a search.
After I ripped the DVD with dvd shrink and put a still image in place of the FBI warning, it gave me about a 20 second black pause before at the start of the movie.
I would like to know what software, if any, I could use to cut the first 20 seconds of the movie before I burn it back to a DVD.
Something that would do video and audio editing I guess you could say. I have tried several but most just do video or audio at the same time. Im not really smart, so it would be nice to be user friendly. LOL.......
Thanks for any help.

The dvd is Mirror has Two Faces. but that shouldnt matter.
It works just fine If I rip and burn as usual. I just want to get rid of that black space.
