Well the current PFP Runco processors do not accept proressive component signals so I would suggest a five your old model is NOT goint to be happy.
Having said that a CRT projector like yours will generally try to show ANY signal it is given. The 933 is a NEC9PG extra in disguise I thinK. It's ideal res is probably 720p in 16:9 aspect, You'll probably need to turn this into RGBHV using a Mike Parker or Key FDig transcoder to do this
