Repair ISO image

I have 2 ISO images that I have downloaded couple years ago. I used to open them with Poweriso then extract them from Poweriso to my hard drive, they are Video files, and used to play them out with no issue at all.

However Now, I am trying to do the same thing. I can open both ISO images with Poweriso, the difference is, one of the ISO image I can extract it from Poweriso to the hard drive and played the videos out. while for the second ISO image I still can open it with Poweriso, but when I try o extract the files to the hard drive I get message:
"Unexpected end of file found"
If I click OK it will proceed extracting the files but the video files will not play out.

From Poweriso, I tried to extract on file at a time to the hard drive, it does extract it with no error previously mentioned  , but the video file will not play out either.
 
I tried with Winiso it is the same issue.

I wonder if the ISO is corrupt and if so whether there is any repair tool for it

Thank you

Try extracting the ISO with something like 7Zip. I have had luck with that.

Have you tried mounting the ISO as a drive and copying the files off?

Use a program like Alcohol 120%. Also, have you tried re-downloading the file, whether from the original source or from your network share where the ISO is stored?

I do not have access to re download the ISO again.
ALcohol requires reboot.. I will reboot the computer later....

I though there might be a software that scans the ISO and repairs the corrupt files

Unless the ISO has a good recovery record within it, which usually they do not, you will not be able to repair it.
Winrar has the ability to repair archives (ISO sometimes also) Open, browse to your .iso, click on it and press the repair button on the toolbar, you'll get a popup: "Treat the corrupt archive as RAR/ZIP" is what you want.
