recently bought a 4805 and as this has Faroudja processing built in I expected to feed it an interlaced dvd signal and let it do the deinterlacing and scaling. however, the manual, and the guys at Sevenoaks say that I should use a progressive scan output from my dvd player. Doing this does seem to give the best picture, but I'm just a little confused as its not what I expected. Does the Faroudja processing handle deinterlacing or just scaling? cheers. ps - I'm using a Pioneer 575 dvd player.
