make arduino tvout initial release work into atmega32

Hi Guys

I'd like to improve my understanding about coding.  i am really stuck working 
tvout library to atmega32.

id like to start basic which is the tvout initial release to help understand 
things step by step.

i believe that the tvout initial release work at atmega328 using the pin 9 and 
8.

so this are the pin configuration
//setup the ports

DDRB |= 0x03;
PORTB &= ~0x02;
PORTB |= 0x02;

// inverted fast pwm mode on timer 1
   TCCR1A = _BV(COM1A1) | _BV(COM1A0) | _BV(WGM11);
   TCCR1B = _BV(WGM13) | _BV(WGM12) | _BV(CS10);
   ICR1 = CYCLES_SCANLINE;
   OCR1A = CYCLES_HORZ_SYNC;
   OCR1B = CYCLES_OUTPUT_START-20;

how to make it work with the atmega32 which is PD5 is OCR1A and PD6?

sorry for my english =D

hope someone help me.

thanks

I also notice there is assembly language at video_gen.cpp.

__asm__ __volatile__ (
      //save PORTB
      "IN      r16,%[port]\n\t"
      "ANDI   r16,0xFD\n\t"

   ".macro output\n\t"
      "BLD   r16,0\n\t"            //output pin of the port here pinB0
      "OUT   %[port],r16\n"         //and on the last line of asm
   ".endm\n"

   ".macro pixeldelay\n\t"            // delay time for setting pixel width
