tv-out flickering problem

i connected arduino to a tv via the tv-out library. http://www.arduino.cc/playground/Main/TVout

it worked fine for couple of weeks but now it only gives flickering, i checked resistors, wires, code, tried different tv-s, basically anything i could think of but the tv only gives random flickering, showing the picture for about one second and then flicker again.

anyone?

okay i figured it out. there is a difference in which order to connect the resistors.
