Reg. background is coming up, but not windows with s-video

Hi all,

Thank you for reading this post.

I have written a very small frame buffer driver for tv, and configured
the registers for NTSC. I am seeing a background either plain color or
color grid as i configure in registers, but i have not been able to
get any windows, i programmed only for GFX window, i am not seeing the
window on tv even after trying for many days. If any one had any
suggestions regarding this issue, please let me know.

Thank you,
