720HD is 1280 x 720 pixels per frame. The highest resolution that the DVD format can support is 720 x 480 pixels per frame for NTSC (or 720 x 576 pixels per frame for PAL), which is at best only 37.5% of the resolution of 720HD.
Multi-format drives can read and write more than one format; e.g., DVDÂ±R(W) (DVD plus-dash recordable and rewritable) is used to refer to drives that can write/rewrite both plus and dash formats, but not necessarily DVD-RAM. Drives marked, DVD Multi Recorder support DVDÂ±R(W) and DVD-RAM.
