Very disappointed 318

I had a problem with the YUV cable from my HD PVR, a son had come off, and no money to fix it, I decided to order a new cable. I was happy to receive it, but from the first connection, a fault occurs: the jack cover of the console side opens. Not good when it's supposed to be resistant.
I noticed a strange effect "Rainbow Sky" on TV, I've tried to mitigate, but impossible to remedy. I thought it had to be on TV.
And this is where the biggest problem of the cable: it was he who made this disgusting indeed! Looks like we watch a tape in full HD!
In short, I am very disappointed with this cable, which will most certainly go back to where it came from. I totally recommend.
