Has anyone noticed this on the DVD?

My copy of the DVD arrived yesterday (along with the CD) and having just ran through a couple of songs with it, there's a little gimmick I'd like to point out just in case no one has noticed yet, or are wanting to know about the DVD before picking it up.

You know how, if you live a country like the UK, Europe or Australia, if you get a DVD release of a film, its audio track is most commonly pitched up a semitone? Well, that's the case with this DVD as well. This was very rare, considering most of the other Celtic Woman DVDs I own are all in their original pitch.

There's nothing about it which poses a problem by all means - I just thought I'd let everyone be aware of it while I could 

Interesting, at the same time another person off of a Celtic Woman group fan page on Facebook posted commented that he got his DVD and that to him the sound quality wasn't like when he heard it on youtube so there right there is something else..
