the problem is in fxtv:

 tvcapture.c:TVCAPTUREStart(), around line 458:

    /*  SETUP CAPTURE PARAMETERS  */

    /*  format  */
...
    /*  input  */
...
    /*  brightness  */
...
    /*  contrast  */

here Randall is resetting the color values each time.  I discussed this with
him, he was doing it because of warnings about the driver easily loosing
state of many values.  If you remove these lines the problem goes away without
any side-effects (that I can see).

Randall, have you attempted to deal with this yet in your source tree?
