I believe the standard NTSC has 525 scan lines, and HDTV is 720 & 1080i.
The native format of DVD is 480i, which is also the operational mode of all traditional televisions and video cameras. However, most DVDs are sourced from film, not digital video. Film is natively 24 frames per second, none-interlaced. When film is converted into a DVD, it's converted to 480i using a 3:2 "pulldown technique".
Most HDTV's out there are able to perform a reverse 3:2 pulldown automatically if it detects film-source material.
