Hey there!
1. There is no way to play things at 1X on a SDTV. I mean, you can set up the screen in its 1X size, BUT IT WILL BE GARBLED AND USELESS. Too small and with the graphics really bad.
2. There is no way to set up the CPS1 + CPS2 in its REAL 2X SIZE in a 4:3 SDTV, without cropping the sides! There is no way really. It is really impossible.
3. The only way is to GIVE IT UP and adopt the LINEAR FILTERING METHOD, and adjust the size to any horizontally width that looks better on the 4:3 SDTV screen.
