[mythtv-users] xorg.conf file for PAL TV output

I'm having trouble outputting to my PAL-I CRT (widescreen) TV.

I have a Mac mini with Intel 945GM chipset. I'm using the Apple
DVI->composite adapter.

This is my xorg.conf file:

Section "Device"
    Identifier    "Intel 945GM"
    Driver        "intel"
#    Option        "Monitor-TMDS-1"    "Configured Monitor"
#    Option        "Monitor-VGA"        "Configured Monitor"
    Option        "Monitor-TV"        "tv"

Section "Monitor"
    Identifier    "tv"
    Option        "Enable"    "true"
    Option        "TV Format"    "PAL"
    Option        "PreferredMode"    "720x576"
    Option        "DPMS"        "false"
    HorizSync    30 - 50
    VertRefresh    50.0
    Modeline    "720x576pali"    13.500 720 760 824 864 576 599 601 625
#    ModeLine    "1024x576pali"    19.750 1024 1056 1152 1264 576 581 586
625 -hsync -vsync interlace
#    DisplaySize    575 325
    DisplaySize    183 146

Section "Screen"
    Identifier    "Configured Screen"
    Monitor        "tv"
    Device        "Intel 945GM"
    DefaultDepth     16
    SubSection    "Display"
        Depth    16
        Modes    "720x576" "480x576"

Can anyone tell me what I'm doing wrong? I see a few flickers, but
ultimately a black screen.

I've looked through many wiki entries, but can't see what I'm doing wrong,
so came here for help.
