I have a Sony dvp-s360 DVD player, and recently I have had troubles with it locking up and skipping forward when playing movies. The screen will become pixelated and the image will freeze for several seconds and then will resume, often times several seconds or minutes ahead of where it was playing. Is anyone familiar with this problem and how to fix it? Or am I in for an expensive repair? A friend with the same player, purchased at about the same time, is also having this problem.
