Thank you for all your help my friend.

Unfortunately, it seems to me that I am a lost cause. Whatever I try to do with these menus, including following your very comprehensive instructions, I just come up against brick walls, time after time.

I think that I am just wasting my time and, more importantly, your time.

I will have to be satisfied with being able to trim the unwanted parts of the video but leave the menus with the unhelpful thumbnail images which were created by the DVD Recorder.

It does seem a great shame that DVDRMP does not have a capability to import .BMP backgrounds straight in without going all the way round the Moon. This would seem to be one of the most basic of editing features which could be needed, along with the ability to change the invisible highlights.
