Shrink problems

[maurrich]

I am having trouble copying DVDs I have recorded recently. I have used both ULEAD and Nero and each time I get error messages such as "inavalid navigation structure". I don't know what that means. Last week I was able to copy some DVDs multiple times with no problem. All of a sudden I can't copy anything. These are disks I have made of various television programs.
Any help or ideas would be appreciated.
Thank you in advance.

Hello maurrich, welcome to the forum.

You want to copy those discs to your HDD or to another disc? Can you clarify the problem a little bit more?
