want to burn 2 ISO files, but fails to play

[thomasjolly]

Trying to combine 2 ISO files, project burns OK, but DVD player says "DISC ERROR." i notice that adding ISO file #1 will include the smaller "MDS" file, and adding the #2 ISO file will not, repeat, will not add its smaller file...Does this smaller file (in ISO image#1) somehow control the overall size, or some other factor, thus causing the disc to fail? Project verifies fine but just won't play. What to do? Couldn't find what i needed in Cynthia's instructions, but this may be my fault...many thanks!

You probably need to extract those ISOs with something like 7-zip and then re-author them together with something like DVD Shrink. Of course we wouldn't have to guess if you provided the log of that burn as per the pink banner at the top of this page
