Thanks for the quick reply. However, I followed the procedure you reference but my new DVD disk does not play in DVD Player.
Here's what I did and what did not work.
Running latest version of Mavericks on 27" iMac with external Superdrive and 4.7 DVDs.
1. Put the non-copy protected DVD, with folder named VIDEO_TS, in the Superdrive. Stopped it from auto-playing.
2. There is plenty of space on my HD.
3. Went to Disk Utility > open
4. On left sidebar, selected the filename of the DVD
5. Chose New Image+ at top, chose destination Desktop, set Image Format to DVD?CD Master, set encryption to none, named new file, selected save to create. This created a .cdr.
6. Ejected disk from SD.
7. to burn new DVD, converted .cdr to .dmg format in Disk Utility: selected file from left sidebar, selected Convert, Image Format compression, Encryption none. This saved a new .dmg file to my Desktop.
8. On Desktop, selected the .dmg file, right-clicked, selected BURN file, which created a new DVD.
9. I ejected the new DVD and reinserted. IT WILL NOT PLAY in DVD Player, even if I launch the Player first and OPEN the file on the new DVD.
Please, what did I do wrong?
