tv scratch lines or something like that

Okay, i have tired and triend to figure this out on my own.
and searched through the memories and i HATE saying that because everyone says that but its true i have. and there are all kinds of memories saying things about scratch effects but i am not sure that is what i am looking for as most images in them are now little red Xs

anyway i use PS7 and Image ready, and was just wandering how to make the old TV lines, vertically, scratchy looking, like in old movies where there is a scratch in the film... i hope this makes sense. could anyone tell me how to do this?

example by dreamsaredead do not take as it is not mine to give away!



thanks in advance :)
sorry if this is in the memories, maybe i am just an idiot. i dont know.
