I haven't had the need to copy a DVD in over a decade and the last time I did it was probably under OS X, possibly even Windows, using some commercial tool. But recently my stepfather came to me with a DVD that had been made from a home video that he wanted several copies of. It is not copy protected in any way, just a plain DVD video disk. I have an external USB DVD drive which seems to work okay, but honestly I barely use it for anything. I tried using Brasero but it seems to read the disk quickly at first and then become progressively slower and slower until it gets to 99% and then stays there for hours and hours. I used the dvdbackup command line program and was able to make a backup and burn it with growisofs with no problem so I'm not sure why Brasero didn't work. Does anyone have any recommendation for a simple GUI DVD copying tool? I'm not worried about breaking copy protection here. I'm fine with the command line tools but I do this so infrequently that it would be nice to have a GUI app that doesn't require me to look up notes or search the internet for instructions to refresh my memory the next time I want to do this in 2036.
Why not just dd it? DVDs have a block size of 2048 bytes, BTW, so any multiple of that should be efficient, eg:
dd if=/dev/the-dvd-device of=my-dvd-image.iso bs=64k progress=status
That should get you a pretty direct indication of the copy speed. And then you can dd the ISO onto another DVD, or mount it or whatever.
