This link below has most of the discs which feature this structure protection on it, and a couple of graphics showing both the "jumping boy" and also the "running boy."

Note that this is a combined list, as it also discusses Sony's ARccOS protection, since they both are very similar in approach. Some believe that Sony sold a license for Sony ArCCos to another distributor, to use this form of protection, which led to the "running boy / jumping boy" protection. Others are convinced there is no relation between the two types of protection. Both have similarities (structure problems with the make-up of the disc). Both also have differences (corruption in the video exits only in the running boy variety).
To quote: "There is a video in VIDEO_TS.VOB where a kid jumps in the air, played over and over. DVD Shrink can't handle this video. It's a hidden video clip which is usually put in the subpictures."
And, for those who wonder as to its actual origin, the "jumping boy" scene is a clip from the movie "Billy Elliot." It is an "extra" of sorts -- a sort of a movie trailer -- which has been deliberately corrupted, and then encoded into the "unreferenced material" on a few recent DVDs.
The discs which have this "jumping boy / running boy" video as an extra often exhibit a complete blackout at the very beginning of any backups, even if one tries to rip only the movie. The blackout usually lasts from 3 to 8 minutes, roughly. If you preview the rip, and see this "black screen", it is easy to use your favorite software to simply "delete" this portion of the video, or to "blank" it out. Even DVDShrink can be used to do this -- once it has been ripped to your hard drive with another program -- as long as you know in advance that it needs to be done.
There have been cases where people assumed that the rip was unsuccessful, as they did not sit and wait patiently for the length of time until the lengthy "blackout intro" finally ran its course. Even worse, there have been people who wrongly assumed they had a bad burn...
This protection first surfaced last winter (December 2004, and January 2005, as I recall).
