Progressive scan question

To reap the benifits of progressive scan, your tv must be able to scan at the rate of 31. Your non hdtvs scan at 16. HDTVs have their own line doubler built in and most times they aren't as good as the outboard ones. Compatability is an issue on some hd sets. Many require the set top box; some of those don't have component in.All sources from 'svhs- in' (dvd & sat.) are doubled(on hd sets) If one doesn't have an HDTV set;keep your present dvd player. 480 interlaced is standard. This means the lines of resolution you are watching are just 1/2 the field alternating. 480 progressive /is the 480 full time./ having been doubled.

A simpler explanition of 3/2 pull down: movies are shot at one rate/ your tv scans at a different rate of speed/frames per second.
