    i cannot get rid of the interference in the video on this 1.1v and i have tried everything!

    i recapped the entire foxlink psu with rubycon caps of the exact uf needed. i also purchased a delta psu to see if the different brand would change anything and it did not. i recapped the entire motherboard except for about 5 of the 22uf caps. i used rubycon on everything except the five in front of the processors. i used 5 nichicon polymer caps there. i soldered a wire to each screw hole of the psu and soldered one wire to the metal outer shell and one to a screw hole on the motherboard(to make sure it was all grounded well). i also recently tried disconnecting the power cables from the dvd drive and harddrive to see if those caused any issues. there was no change. i have an open xenuim chip on it and on a 1.6v. i also have the same bioses on both(evo and cerbios). the 1.6 has a perfectly clear and crisp pic. it is flawless when i boot with cerbios. but i just cannot get rid of the interference on the 1.1v. i'm using the xedusa+ hdmi adapter. i have already tried exchanging it for another one and have the exact same problem. i also have the official microsoft hd pack and have tried it and still get interference on it. about the only thing that does not give me interference is a monster xbox hd cable but, i do not like the color display when i use that cable. the interference on the xedusa is usually in the form of diagonal or vertical lines that run across the screen during 480p output. 720p and 1080i seem to be fine. any and all tips and help is appreciated! even a good educated guess would be appreciated! oh, and i also have the same problems with unmodified 1.0 xboxs.

    i have heard about this type of issue before.
    cerbios screws up the video on some games when you use 480 output on 1.6 consoles.
    also the hdmi adapter you have has a known issue with some box revisions.

    but you should know that because you posted on OGXBOX forum where it was previously mentioned.
    the cerbios issue is an obvious one, it's enforcing a specific video mode while some games try to dynamically tweak the mode for specific effects.
    the hdmi adapter is harder to pin down - probably the chip in it doesnt frame-buffer a screen so if the sync rate is slightly off you get tearing or bending.
    you cant win with that because if you use a hdmi chip that buffers you add a lag between the console and your screen.

      cerbios on the 1.6v is perfect. takes care of all the video issues that revision is known for on the games i have tested so far. very nice clean and crisp pic with no interference or jailbars. and the only issue i have seen this adapter have a known issue with is the 1.0v and it only affects the sound there.

          i didn't either. but there apparently is. the mclassic somehow fixes it on the 1.0v though. that's what stone age gamer and the behar bros claimed and i tested it. it turns out to be true. the mclassic is also something everyone needs to use with these consoles. the youtube videos don't do it justice when trying to show how much better that device makes an image look on these retro consoles.

            well, it could be down to grounding or maybe differences in DC blocking (capacitors)
            in the cables/adapters maybe.
