However, the subject of pitch correction was discussed at length around the time my DVDs were released. Citizen first pointed it out to me, and I noticed it when I compared the recording of the ANH mono mix - taken from a PAL TV broadcast and had not been pitch corrected - with the VHS source I used in the laserdisc transfer.

So the parts of Building Empire that are taken from my laserdisc transfer have the correct pitch.
The most reliable way to confirm if the pitch increase is there or not - for those of us who don't have "perfect pitch" - is to carry out a listening test on two samples (I find it's more noticable in music than dialogue).
