Are DVDs really 480p? 480p vs. 720p question. - AVS Forum
Jan 28, 2009 · The ultimate way to display a standard DVD on an HD display is via an "upscaling DVD player", which reads the 480i signal, converts to 480p, then "scales" the 480p output to 720p, 1080i, or 1080p.

True inverse telecine of 1080i film-based material displayed on a 1080p display will probably be the new high-water mark, along with true 1080p source, natch.
