Ever wonder what the suffix 'i' and 'p' in resolutions?  The short answer is the number represents the 'Vertical' lines of resolution
(see my TV resolution post for more info), and the suffix letter refers to the scanning process.  'I' is short for 'Interlaced'; the 'P'
suffix is short for 'Progressive'... Read more on the subject on my "Home Theater Examiner" site
