Please explain this to me. In the us they have HDTV which is a much higher resolution image right, and they have progressive scan, is this the same thing? Like the gamecube has progressive scan, if I feed this to a HDTV do I then get a higher resolution picture. Do they have high resolution signals coming from the dvd players and computer or do the tv´s have line doublers or something. Could I get an HDTV from my pioneer 737 dvd player, or would it just have some progressive scan image?
