That's similar to turning up a radio's volume control all the way up, you get distortion.

What DVD player are you using? The player might suffer from chroma upsampling error, an MPEG decoder error that plagued many early DVD players and is still evident in cheap players. It's most evident in red, causing horizontal streaking/blur in the picture's resulting color. Some affected players really exhibit it worse than others.
