Just got an iPod AV cable. I hooked it up to my TV. I hear sound and see video, but it is in black and white. How do I get it in color? It's in NTSC now. I tried it in PAL, but it still stayed in black and white and the video moved up and down. The color shows on my mom's iPod 5th generation video, but I have an iPod touch. Any advice on getting it working? It's the AV cable that has the blue, green, white, and red cables.
