For your information:
After DMS3 install on V3 I still had the green effect on dvd playback using the RGB cable.
Screen Settings were SIZE=4:3 & COMPONENT=RGB.
Then, I have choosed SIZE=FULL & COMPONENT=Y C B, played the movie - the picture was bad as expected.
Then, I have choosed again COMPONENT=RGB, and it played good! without the green effect, strange...
