I only have Amy's CIA, and I agree that the intro is ridiculously short (and the chaptering could have been a little more careful in spots).
You know, my DVD and TV are both acting up. My DVD player is now 7 years old, and it does funny things like making whirring sounds when I insert some DVDs (although if I take them out and put them in later it's sometimes fine). It doesn't play all discs, and there's often no rhyme or reason why it's not playing even some pressed DVDs right now. And my TV, the same age, is now making popping noises!
One suggestion: do the old unplug and wait 20, 30, or 60 seconds, then replug it back in.
