In a large resealable plastic bag, combine the vinegar, wine, 1 teaspoon oil, chili powder, horseradish, dill, garlic powder and salt. Add the pork chops; seal bag and turn to coat. Refrigerate for eight hours or overnight, turning occasionally.
Drain and discard marinade. In a large nonstick skillet over medium heat, cook chops in remaining oil for 4 to 5 minutes on each side or until a meat thermometer reads 145�F. Remove from the heat and let stand for 5 minutes.
