Hi Phil,
You say Dans code works but you need to verify this with someone. A lot of codes haven't been tested on the system they were meant for. As I said it never locked for me. Btw, if your sync is suppressed you should have done the agc hack or your signal will be stuffed before it reaches the decoder. Auto invert, simply inverts the video signal back to the correct polarity. If you need any help with Paldig.asm I can help you modify it for suppressed sync.
Change HORLINEA like this to sample at start of colorburst:

movlw MAKEBURST
btfss VideoMode,DEC
movlw PASSVIDEO
movwf PORTB ; Ventana burst=5.8us
; t=4.6
