It just happens to be coincidence that nearly all countries that use PAL color encoding for TV also use 50/625, and all that use NTSC use 60/525.
Its not a coincidence, its an artifact of the power source and the color information in the country, you are acting as if they resolution was decided independently, it most definitely wasn't.
DVD uses MPEG 2 compression with a YUV color model.
Which part of MPEG2 D1 streams did you not understand?
Because it's digital it has nothing to do with PAL/NTSC (the color encoding systems), however, it is common for
DVD producers to use the terms PAL and NTSC to refer to the different resolution and refresh rates, presumably out of laziness.
No because they are playing it on NTSC or PAL TVs. Digital cable and digital satellites TV also arent analog, but digital, but are still broadcast in a form that is viewed as PAL or NTSC formats. DVRs the same. As for the Pal 60 format you talked about, or the PAL I, PAL N, etc all of them are based on different frame rates, sizes because of local conditions, this basically proves my point not yours. The same with the Japanese version of NTSC. In addition, understand NTSC started out as a monochrome format at 60 Fields, and 525 lines (not all viewable), there was no color, so implying that NTSC only has to do with color is silly, it was a monochrome spec (adopted in 1941), we later added the color carrier wave with NTSC II, and of course now with NTSC III (which was adopted due to digital cable switchers in the 1980s.
I hope that clears things up.
No, it looks like you just were throwing mud. DVDs are sold as PAL and NTSC formats for a reason, even D-VHS is sold in PAL and NTSC formats unfortunately. With Blu-Ray and HD DVD we are finally getting away from multiple formats, but until then its important to see which format is supported on the labels.
