Subtitles in overlay mode - need help

Hello.
I have Matrox g500 millenium graphic card and am runnig a lcd and tv on it. I just cannot find the right overlay mode, where I could see the subtitles on tv. When I take the preferences from the prevous version (overlay mode 1, draw subtitles to overlay, disable yv12 format...) i get strange lines on the monitor and also on my tv, that cannot be read. All other overlay modes show no subtitles on tv.

Please help me, because i really need subtitles on the tv.
Please
Thanks
