I am about to upgrade my Toshiba 210 DVD player for either a Toshiba 530 or Pioneer 565. Both £200! Pioneer has upper hand on formats, being DVD-a & SACD (Toch DVD-A only) but Toshiba appears to have more comprehensive Progressive Scan capabilities (according to LEConcepts.com). 1. What exactly does PS do? 2. Will I need it with my regular widescreen TV or is it something reserved for plasma & rear projection TVs?
