Basically I recorded a video on my mobile phone of my friends band, well two videos to be exact and the sound quality is not great and the lightings not amazing, also due to me being quite new to the phone (its 5 weeks old) I turned it on its side by accident, but I can sort all that out on Windows Movie Maker. My main problem that has had me pulling out my hair is that theres a grey trailing line that moves from right to left of the video every few seconds, like the one you get when a video cassette is damaged or near the end. Is there anyway to remove this? I'd really appreciate any help as I promised my friend I would post the video but it's not worth at it at the moment.

Any thoughts would be fantastic.
