Without a Paddle

Well, it may not be a creek but there's still too much sewage to swim in after the recent flood. However that's not the only thing I'm refering to in the title. You'll notice some line over on the right, they are appearing on every frame now and no matter what I try (and believe me I've tried everything I can think of) it just won't go. Today of all days too, I have just agreed to do a shoot tomorrow that coud be a major feather in my cap. I won't say too much just in case I cock it up but you'll notice if I get it right and it's nothing like I've tried before, not even a little bit.

Any ideas about the lines? Anyone?
