Kaffeine/xine motion blur

Hello all, When watching home-made DVDs from my DV camera as the source, I see a lot of blurring in fast motion scenes. The DVDs look fine on a standard DVD player, but when xine or kaffeine tries to play it, I get a lot of motion blurs. I'm not sure if this is an deinterlacing issue or not. I managaed to get those lines to go away when I turned on deinterlacing :) Anyone else have a solution to this? -Khanh
