Avi render not framed right

[genesis1]

Not sure how to title this thread, but I have just noticed something that has never appeared before in my animations.
There seems to be something wrong with the very edge of the picture, as if the last row of pixals has not been processed correctly, or the camera frame is wrong. There is a white line right at the very edge at the bottom of the frame that flickers in the animation. I've tried altering the camera settings but cannot get rid of it.
Not sure what I have done wrong that has made this appear. Anyone else had this problem? Its as if the video has rendered larger than the frame of the camera. Any ideas anyone?

Can anyone verify what the frame setting should be for 800x600 just in case I've altered something by mistake. It says on my frame size: 0.5906" for 800x600.

Have you tried outputting a sequence instead of a video file, issues like with codecs are one of the many reasons not to render to video -

Yes, I can actualy see it in the preview window. I notice it when using the classic camera. When the resulting image stream is put together it results ina flickering line at the bottom, and to the right side of the frame. I can crop it out, but its realy annoying to have this fault. Don't know whats causing this, as I never used to get this.

Here is the line in question that is visible in the renders.
You will see a faint white line at the bottom and to the right. This flickers in the animation.

Looks to me like you may have Limited Region ("l" hotkey) enabled by accident.

(will limited region do that?)
Are you using a projection or background image?

The scene is set up with a wall object, a floor object, The tardis Object and character object. There are no background projections, only textures applied to objects. This does not occur when using the new perspective camera, only the 'Classic' camera.
