I know this was a long time ago. But when Cathe's Ab Hits dvd was first made available, I ordered it. Then I received a second copy of it in a cardboard sleeve and wondered why. I thought it was just a duplicate, so I gave it to my sister, and never thought about the extra copy until now. Since TLP's first batch of dvd's are faulty and they are sending out replacements, it just dawned on me that the 2nd copy of Ab Hits that I received must have been a replacement for the 1st one because something was wrong with it. However I can't find the problem with the 1st one. Does anyone know what was originally wrong with it?
