I see two problems with your X configuration:
0) You're using an invalid value for the TVOutFormat parameter:
(**) NVIDIA(0): Unknown TVOutFormat value. Known values are "SVIDEO" and
(**) NVIDIA(0): "COMPOSITE"

1) You've requested a 1080i in the Screen section, however you never provided a corresponding 1080i modeline. You either need to replace 1080i with a real mode (1920x1080, etc), or provide a 1080i modeline in the Monitor section of your X configuration.

If making the changes above still does not result in what you expect, please start X with the following command:
startx -- -logverbose 5

and then generate and provide an updated bug report.

Thanks,
Lonni
