How to create video clips from instructional dvd?

Sorry it didn’t work for you. On the DVD I used a capture software on I was able to go to full screen once the viewer on the DVD started. The capture software did a fairly good job of capturing this.
I haven’t worked with securom protected DVDs’ but that might be what you have .
You can read these links if you like.

I would be interested in seeing what files & folders are on this disc.
This is what was on the DVD I used the capture software on:
The .iso & .mds were added to the folder by me . The image is actually a folder I made of the actual disc. So it has those additional files. I could probably find the disc but it would have everything else the same.
