    So i bought a 3.50
    cable from ebay
    that plugs into the back of my Powermac G4 and
    allows it to be put on a tv via svideo or composite

    vga to svideo/composite

    so i plug it in
    and i get nothing on the TV

    so like idk what i did wrong

    i adjusted the video on the Powermac to
    800 x 600 (or the smallest it would go)
    and i still get nothing
    except for a black screen?

    DUAL 500 MHZ

    Try refreshing the displays in system preferences and see if it works...

    Are you 100% sure it works with your G4?

    The video card in my Mac Pro is so awful it can't even connect to a TV.

    Video cards of that vintage do not support S-video/composite output via the VGA port.

    well are there any other ways i could connect this computer
    to a tv

    i have an iBook 1.42
    if i used the Mini VGA to VGA then VGA to composite
    would that work?

    (like showing a brief QT movie)

    The video card does not output S-video or composite AT ALL.

    Such adapters are meant for use with specific video cards on later Mac's.
