I am new to this forum and this is my first post, hope its in the right place, sorry for any inconvenience if it is.
i tried to ‘back up’ a dvd (that i already own) the other day but came up against a problem, i have 2 programs on my pc that will shrink and take the protection off the dvd, one of them just could not ‘analyse’ the dvd and the other was able to but the ‘compression’ was down to about 15% which is not good, and this mystified me as it should not be that much.
So i decided to ‘explore’ the dvd and found that the movie was on the dvd about 5 times but with slightly different ‘running times’ so i decided instead of doing a ‘whole disc’ copy i would use the ‘re-author/customise’ option in these ‘copy programs’, i decided to copy the longest running time movie on the dvd.
unfortunately after the dvd was burned and i played the movie in my dvd player i noticed that a chunk of the movie was missing and after the end credits a part of the movie was repeated (not the missing part).
i can only assume that the 5 movies on the dvd (original) has different parts missing but when played in a dvd player it some how takes all the correct parts from the different versions to play the whole movie.
anybody come across this before, how can this be done (all those slightly the same movies on one dvd) and does any body know a way around it.
