    Hello,
    I have tuned my CRT NEC 6100 via Avai dvd. When I watch a dvd the picture looks great. When I watch hdtv cable it looks very grainy and ther are wavey lines like the contrast is set too high. I am running everything through a Maxx 100 or Focus Centerstage 1 scaler set at 720P.

    Do I need to change inputs on the scaler and tune each input with the dvd. I am running progressive composite for the cabel tv and interlaced for the dvd. So you would think that the cable would have a better picture.

    I hope you guys can help me figure out where the problem is.

    Thanks

    Hi,

    A bit more information would be helpful.

    I can't quite see why wavy lines and grain should correlate with high contrast.

    And I guess you mean progressive component?

    I use a CS-1, and find that the output settings are independent of the inputs (given sources set at the same level). i.e if I set up on say s-video b, then component a is fine.

    Generally, black levels creep up and down between dvds and broadcast stations.
