    First off let me say this forum group is amazing. I was transversing the site to see if I could find my problem already solved, and alothough that was fruitless I learned many many other things I didn't even know I didn't know. [​IMG] I look forward to reading through the forums as my time allows. There is a bunch of knowledge here.

    I made this post on a google group site, but the activity looks pretty non-existent.

    Recently purchase a Sony AV receiver / DVD /Speaker package. I don't
    have the make now as I am at work. The receiver and dvd player are
    seperate components. I also have a hd COX dvr hooked to the receiver.
    The receiver out goes to a Sharp DT-400 projector.

    Problem: I am getting a audio signal in my picture when playing dvds.
    The more "musical" the more signal. Chronicles of Riddick = almost
    nothing. Star Wars PM = worse when the orchestra gets going. Rush in
    Rio (concert video) = very very bad. The signal manifests as red and
    yellow (mostly red) horizontal lines going across the screen to the
    beat of the music.

    I am using composite cables (high end THX certified) for video and
    coaxil for audio. I can also use HDMI or analog, but dont want to
    analog and can't figure out how to get the HDMI to work. Also have
    optical option for audio as well as stereo.

    What's trippy is that I have totally disconnected the sound from the
    dvd player and the distortion is still there in rhythm with the beat.
    With no audio at all hooked up, only composite video! I have also
    switched out the composite cables with a different type (less high
    end). I have also changed the video in port from dvd in to video 2 in
    and video 3 in.

    I am not getting this problem from the hd cox dvr.

    Since I want help and not pride [​IMG] I might as well admit that the
    receiver and dvd both have tons of menu settings that I screwed around
    that I dont understand. I did do a master reset on both though to the set
    the settings back to factory defaults.

    Thanks for any advice. Don't worry about admonishments, my wife has
    taken care of that.

    My guess is that the dvd component needs replacement

    Thanks again,

    Hi Aaron. Welcome to HTF ! [​IMG]

    My best guess is that your DVD player has an internal problem and is injecting noise into the video circuits from the audio side.

    To test this: borrow another DVD player or go buy a inexpensive-but-name-brand unit from a place with a 30 day return policy and try it.

    I am also assuming when you say "high end composite" you really mean "component" (3 RCA wires).

    Try another DVD player if you can and let us know how it works.
