I have an optical disk (DVD) with an important video file on it, and I don't have a backup. I can play back the video file (an mkv file, playing back with gnome-mplayer) without any problems, but I would like to copy the file over to my hard drive and then back it up to the cloud.
When I try to copy the file over to my hard disk, I get an error:
+ [~] $ cp -v /run/media/alex/DVD1/video.mkv Videos/
'/run/media/alex/DVD1/video.mkv' -> 'Videos/video.mkv'
cp: error reading '/run/media/alex/DVD1/video.mkv': Input/output error
Any ideas?

try ddrescue to deal with discs that have read errors on them
also check dmesg if any I/O error messages appeared
in case of optical disc this can also be dirt, smudge or a scratch that might be able to buff out, or another drive might be able to read it better
but you should ddrescue first, try physical things later

there are some video players that allow you to playback and record at the same time (vlc for example).
Since you mentioned you can still play the video, then you ought to be able to record the video somewhere else, effectively making a copy of it.
I'm not familiar with gnome-mplayer though.

Permission problem?
ls -l /run/media/alex/DVD1/video.mkv
You might also use the complete out path
cp /run/media/alex/DVD1/video.mkv ~/Videos/

It would not seem so, but is there any chance the disk is protected with CSS?
As an experiment, try dd if=/run/media/alex/DVD1/video.mkv of=/dev/null
Should that work, try dd if=/run/media/alex/DVD1/video.mkv of=~/Videos/video.mkv
Obligatory note on dd. It has not earned the nickname Disk Destroyer without reason. The usage I provided is benign, but always, always be careful with dd and re-check your command line at least twice.

Tried all of the above, ddrescue was the solution that worked for me.
