Computers no longer read some dvds(help)

[aaaaa]

Hello everybody!I've been desperately searching for a solution to my problem(s)-well,it's basically one giant beast with too many heads-I do not know where to begin.I have posted a message here

https://forum.videohelp.com/viewtopic.php?t=304834


things are getting worse.I have some dvds that were not properly finalized and standalone dvd players couldn't play them.But at least,computers were able to play them.Suddenly,this is no longer the case.I can't play the dvds on computers anymore!They just can't read them!Every time I try to watch a dvd, I get this message that the last time this disc was played,the process was interrupted-and it has 2 choices-playing the dvd from the beginning or continuing from the last scene.But no matter what I choose,nothing works.




Any idea what has happened?What can I do??

You could try cleaning the laser lens. That might allow the computer to read the discs again.

If you are having the same problem on a standalone AND multiple computers, then it sounds like bad discs.
