converting video help

I would appreciate any and all help.
I have purchased a peachpit dvd, learnbyvideo photoshop cs5.
The DVD can only be viewed through the computer. When I instert the DVD a start button comes up, clicking on that loads the program and all the videos can be viewed.
The problem is I want to be able to convert the video files to .avi or .mp4 so that I can see them on another "easy to carry" device, such a ipad, tablet, or phone. I do not always have my computer available.

However, no matter what I do, I can not find the files on the disc to convert them to a format that can be viewed other than inserting the disc and viewing them this way., which is very inconvenient. I tried using toast titanium 11 as well as visual hub, but to no avail. is there anyway that anyone can help me figure out how to find these files on the DVD and convert them to a avi or mp4 for another viewing option?

I have purchased all programs legally, i am not looking to upload them as a torrent or share them in anyway online, I just really want to use them to learn the videos as quickly as I can as I travel too and from work. If anyone can help me, please, I would be greatly appreciated. I googled, searched, read the titanium manual cover to cover, I am afraid I am missing something so simple.

Thank you sooo much in advance- I hope someone can help me figure out this problem that has been frustrating me for days.

Thanks again
Robert.
