Your "Boss" have written a very nice guide to PAL and NTSC

He seems to agree with me.

Mainly due to the NTSC 3:2 pulldown problem.

Among Pro TV and Film people I have never heard anyone prefer the "Never Twice the Same Colour" format.

So I am puzzled with your experience. Please give a few names of DVDs.
Using two discs reduce the space problem.

The 4% is a problem. But playing back at 24fps solve that.

And Mozart used an A of 422 Hz, not the 440 Hz we often use today. The A have moved a lot in the history of music, and 422Hz is 4% below 440 Hz.

So these is not an absolute A, it is a compromise.
