Everybody likes multimedia so here is some for you.
What is this?
http://www.youtube.com/watch?v=7LfNrGHdMkI&feature=youtube_gdata
And can anything be done about it?


Light horizontal bars/lines roll up the screen bottom to top and its particularly pronounced in really dark scenes especially with warm tones. It was shot with my phone camera so the quality was poor to start. The only way I could make it visible was to turn it
sepia. Then YouTube sucked more quality from it. So to see this you have to set it for 480p and make if full screen.
Then focus your attention on the cheek and forehead. You should see something faint moving from cheek to forehead.

Even though you may only see it on the right side it spans the width of the screen.
I'm betting someone will know immediately.

That is exactly what it looks like except it doesn't distort the picture.
The odd is that I didn't get it with my 1271 but I'll try some of the suggestions there.
