Default Re: 720x576 TV-out with Chrontel 7007

The problem are not the capabilities of the encoder chip, but the modeline generated by the nvidia driver.

The CH7007 mode 19 wants 800 horizontal pixel. The driver configures the geforce2 chip to send only 720.
In modelines it should be
modeline "800x600" 29.5 800 ... ... 944 600 ... ... 625
or (to not exceed the visible region)
modeline "768x576" 29.5 768 ... ... 944 576 ... ... 625
but the driver uses
modeline "720x576" 29.5 720 ... ... 944 576 ... ... 625
resulting in black borders on the sides.
