Corrupted DVD files help me

Hi m8s

I have a DVD-RW that has some AVI files. The disk started to have problems and I decided to transfer the files before it was too late, but one of them was impossible to copy. I have used Isobuster and Arrowkey CD/DVD inpector and I have the file now on my hard disk. Both programs reported different fails but Inspector did a better job in my opinion because the after trying to play the file with BSplayer I got “corrupted video file, seeking will be slow” message in the one extracted using Isobuster but the one from Inspector plays well. I am still concerned about the fails that this video file still can have and like to know if it is possible to find a program that can diagnose a video file and repair it in case that it is damaged. Do you know something good that can do this?

Thank you.
