Query: They go boom

I must admit that it's a great DVD, but I disagree with the other reviewer that the new sound on "They go boom" is a revelation. They replaced the optical soundtrack with the original sound-on-disc soundtrack, but I think the optical one should have been better, because now the sound is terribly out of sync. And that's a shame, because otherwise I should have rated this DVD 5 instead of 4 stars. Nevertheless I think it's a great DVD.
