Vegas 6 - Audio Noise/Buzz/Hum without audio track

[sdsumike619]

It seems like I remember reading somewhere that if the colors are off the charts that they can cause audible noise on a television (not sure what the technical term for this is called) Apparently, the bookspine look of "Measure 2" is causing this to happen. All I did was create the Text, used track motion to rotate it -90 degrees and then used the placement tool in the text editor to position it. - Why the anomaly on the scope?





Thanks

Also, is there some way to make those PNG images of the chord grids easier to see on the screen, i.e., less flicker?
