LVW5005 How to edit chapters

I am trying to figure out how to edit recorded chapters on a DVD recording. I did a timer recording and the program ended half and hour earlier. Now I want to delete the last half hour of the recording.

You can easily do this on a PC using DVD shrink (freeware). There are many guides on the web for DVD shrink.

I don’t have a pc dvd recorder, so I guess what I am hearing is that cannot be done on the 5005.
