I used VGA to component with an Audio Authority for a year and did
like the quality.
However, my current setup is using a GeForce 6200 with a bundled
component out adapter. To get the nvidia drivers to output an HD
signal over the component output, you put this into the device
section xorg.conf :
Option "TVStandard" "HD720p"
Option "ConnectedMonitor" "TV"
And put a 720p modeline into the screen section, and you've got 720p
output. I think its superior to the Audio Authority.
However, with the 8174 driver, if you put HD720p as the TVStandard,
it will not accept any screen modes at all, causing x not to launch.
So thats the problem. Works great with 7676.
