Tvout Pin Changing can not find?

Hello i learn how to do the Tvout from the arduino to TV and it's awesome i have a small project that requires D9 and the Tvout uses D9. I try to search online in where i can find how to change the D9 to D6 and no luck i went through all the coding unless i miss something i can not find it can someone please help me out? Thank you.

The Video and Sync pins are set in hardware_setup.h:

#elif defined(__AVR_ATmega8__) || defined(__AVR_ATmega88__) || defined(__AVR_ATmega168P__) || defined(__AVR_ATmega168__) || defined(__AVR_ATmega328P__) || defined(__AVR_ATmega328__)
#define	_VID_DDR	DDRB
#define	_VID_PIN	0
#define _SYNC_DDR	DDRB
#define _SYNC_PIN	1
#define _ANDI_HWS	"andi	r16,0xFD\n"
#define _BLD_HWS	"bld	r16,0\n\t"

You need the port name and bit number of the two pins you want to use. The defaults are PORTB bits 0 and 1. For the 'andi' value use the binary inverse of the SYNC bit: 0->0xFE, 1->0xFD, 2->0xFB... For the 'bld' value use the VID pin number.

Thank you John i did miss that.
