This DVD has a bunch of drama skits, PV, event videos and the opening movie. The name is wrong too. Further info here:

I'm not sure what the current standards are for DVDs since this one has one music video, but it doesn't seem really needed here. Similar preorder DVDs are included with almost every recent Tales games. If nobody misses this I'm going to disable it.
