Strange burned DVD problem! Need help!



I just bought a external DVD burner just a few days ago, and I burned a DVD that for some reason playbacks on my DVD player (one for the TV) horribly, it looks exactly like a bad reception on an antenna TV. It plays back in black and white and the screen skips with thick black lines and the screen seems to move upwards with these “lines”. It’s irritating, I’ve wasted two DVD+Rs thinking maybe one of the DVDs were defected. They are Sony DVD+Rs (up to 4x speed compatibilty). I need help.
