I have a kv-30hs420 crt and a ps3 connected to it via hdmi on input #7 running at 1080i. Now If I understand right adjusting MID3 will only adjsut for the hdmi input which is the input #7 port right? Ok now I got that somewhat adjusted for now until I get avia, but now I want to adjust the HSIZ, HPOS, etc for say my input #2 which is composite inputs for my sega dreamcast which runs at 480i. My question is what group area do i go in the service menu to adjsut some settings for the dreamcast without changing settings for the hdmi input #7 where the ps3 is at?

I dont know if you guys are gonna say MID3 because I went into MID3 while running the dreamcast of course and while moving the settings in MID3 nothing was happening, but if I go to... cant remember if its 2170d-1 or d-2 but the screen was changing in there. Thanks....
