I will be purchasing a 42" plasma screen in the near future. Right now my PS2 is connected to my amplifier thru the front audio/video jacks of my VCR. This is working just fine. Will I have to make any changes to my current set-up, other than changing the resolution? in the GT4 options menu? Also, is it best to continue using the 4:3 ratio even though the screen is 16:9? My GT4 is NA(Canada).
