Cut out a piece of movie

Can you tell me the best way to cut out unwanted piece of movie from the original DVD, but in such way so after removal of that unwanted piece I could burn the whole movie to DVDR without that unnecessary scene?
Do I have to cut out the whole cell or is it possible to cut out only a part of it?
Will the audio and subtitles be also removed after the removal of video?

Vobrator can be used to chop bits out of a movie, but I believe it can only do it by Cell. as you suggested.

If you converting the DVD to fit to a DVDR with a section removed, you can try using TMPGenc to re-encode as in it you can select the section you wish to encode only.

What about subtitles?
Is it possible remove exactly the same amount of audio + video+subtitles?

I’d like split DVD to 2 DVDR (at the VOB level) without re-encoding but with a section removed.

This would put the subs out but the amount of time you chopped out. You can edit your subs file manually to fix the problem. A big job really.
