I've never seen a disc that's programmed to have resume. If it were possible, I think someone would have done it by now. What we have are a few discs which are authored in basic mode. Those have resume just like SD-DVDs without requiring any special programming, but they can't have the interactive menus and other features that most discs have.
Then we have some discs with a bookmark feature, which is hardly a substitute for resume. The idea with resume is that you should be able to resume watching the movie just by pressing play. In bed I use a portable DVD player and I just hit the power button if I get too sleepy. The next night I just hit the play button and I'm right back where I was.
With bookmarks it takes about 20 button presses to get the movie going again. You have to start playing the disc, wait for the menu to come up, start playing the movie, wait through all the FBI warnings and stuff, bring the menu up again, navigate into a submenu and then a sub-submenu, select the bookmark, and then exit the menu.
