I've only noticed it on the Tagged Classics DVD releases, but I only came across it while trying to mux together one of the two-disc WrestleMania releases so I'm going to have to go back and check everything else.
The last cell is only three or four seconds long, and doesn't rip. I have to turn the minimum length down to 0 in the preferences, and manually rip that cell, then mux it in with the rest of the title.
