[Copying DVD with errors]

It seems that the solution was, in fact, cleaning the DVD .

After that, ImgBurn was able to read the whole disc.

 

As this DVD never played well on my DVD Player (it "stucks" frequently), I always assumed that there were errors on the disc (although I am aware that my DVD player is not exactly top quality...).

 

Anyway, thank you all for the suggestions, which are certainly useful.

[Copying DVD with errors]

I have this non-commercial video DVD with a few errors.

When I try to create an ISO image, I get a message like the following:

 

I/O Error!

[...]

Interpretation: Unrecovered Read Error

 

If tell ImgBurn to ignore these errors, will the resulting ISO image be a valid one? If I burn that image into a blank DVD, should I be able to play the movie on a common DVD Player?
