well, I disconnected the hd tuner to make sure it wasnt giving any electromagnetic disturbance, unplugged the mic, gps, RCAs, ups dongle and made sure my ground connection was solid. Booted up, and the pioneer screens look flawless, but I still have some shitty picture quality for DVD and my hd iPhone videos.. It looks worse than a boss or Pyle screen to me to be honest. I said last night, fuck it I don't watch movies in the car anyway but then woke up and said why did I pay so much for a shitty screen. Does anyone think it may be defective?
