I read books to enjoy them. Not to microscopically examine the pixels on my eReader.
Europe and some other places use 576 line DVDs. Also for NTSC you need Progressive and suitable source DVDs or else not only are they only 480 line, but have 3:2 pull down artefacts if the 24 fps film was converted to NTSC video before encoding. PAL DVD quality is unaffected by progressive or not.

I still watch the odd VHS (about 480 line NTSC and 576 lines PAL /SECAM) only about 250 horizontal resolution unless a local S-Video recording (nearly 400). NTSC analogue video/VHS is seriously poorer colour than PAL too, but it was about 16 years earlier! My older HDTVs had component, SCART (RGB or composite), Y/C and composite, VGA and 4x HDMI. Latest TV only has 2 x HDMI, so I have a Yamaha Home Theatre (Theater) with 4x HDMI in and some adaptors for VGA, component, S-Video(=Y/C) and composite. Don't need the RGB one because the Philips BD player plays all regions DVD (but only local BD).

I remember the rubbish UK 405 lines (378 visible lines, 625 = 576 and 525 = 480, hence VGA was 480 lines). It rand from 1936 to 1985 with a 1939 to 1946 gap. Political nonsense restarting it in 1946 for only 300 TV sets instead of USA 525 with 50 instead of 60, or waiting 2 years for 625. The USA and several European countries used 441 lines before 625. After WWII Europe used 625, except for France and Belgium (819). The 1080 line visible HD is based on Japan NHK 1125 line hybrid HD (1080 visible). HD is a bigger mess of standards than Analogue TV.


It's annoying when a BBC or European DVD recording is mysteriously only "region 0" which is usually NTSC.
