Hi, I bought a Zidoo x9 on the Amazon portal. I have an old TV without the possibility of using the HDMI and I wanted to connect it with the AV cable but I have not found in the package. I tried to buy one but it does not work, maybe because the ground/right/left/video connections do not match. Can you help me? Why was not there in the pack? Where can I order it compatible? Thank you... Giuseppe
