Unfortunately, I had a problem with DVD Shrink, and I went back to DVD Decrypter, to pull out the VOBs, even though they can not be fast forwarded or rewound on the WD HD Media player I am using. Time was of the essence to finish the project to have some home movies on HDD, for the family, and I did not want to spend time troubleshooting why DVD Shrink was hanging up writing .iso file even though the program would preview and analyze the tracks. . .
If anyone has the ImgBurn solution, as far as which files I would needto select for extracting different tracks or home video segments, to create "MEDIA PLAYER" playable .iso files I would still like to know. If you read the original post, this does not have to do with creating menus, or reauthoring DVDs, but creating playable .iso files for use with a USB HDD media player that can be hooked up to an HD TV via the HDMI port. . . I am sorry if that was not clear in the original post. I have again attached a sample of a multi-session DVD of home video clips for clarifying DVD structure.
