I have not tried it myself, but the video on a DVD is already in MPEG
format, so you do not need to "repair" the file that you ripped.
However, when you are encoding, you should add -vf harddup to your command
line. What you actually want is that the duplicate frames NOT be dropped.
See the manual for details. I do not remember if the harrdup filter is
meaningful with -ovc copy, but you can try it.
