I recently started going through my DVDs to clean up some stuff like inconsistent titles on my manual dvds and such.  I discovered a handful of DVDs that I can't actually click on.  they exist on my online profile, and their titles are on my list, but when I click or scroll past one, it brings up the loading bar and jumps me back to the top of my list without even showing an image or anything.... 

any ideas?

edit: I just tried to search for one of the bad DVDs - and it found it, then infinitely tried to load something and crashed dvd profiler altogether....

I've seen this happen once or twice: you can use the Database Repair Utility to fix this.
