Older ISO files not readable

[acefentur]

Hello,

 

Strange things happened to my blu-ray collection.

 

I have bought a few blu-ray disk and recoded them to a new blu-ray iso folder using tsmuxer and imgburn.

I use these iso's on my media center as virtual disk. But those made before august 2009 won't mount now.

When opening some corupted images with imgburn, there seems to be a fault with the file and folder structure. (UDF or ISO or whatever that structure may be)

 

As I watch the properties in my computer of the mounted (and corupted) iso file, I see it size, but not the file structure.

 

I mount with slysoft clonedrive. I have tried alcohol as well with the same problems.

 

Anyone can point me in the good direction ?

 

Thanks for reading.
