I have a 36" Sony XBR-400 and just bought "The Simpsons" - Season 2 DVD set. The picture looks horrible. Lots of line shifting and every so often the picture starts to blur - especially when the characters are drawn in a long shot, for some strange reason. The DVDs are not defective as they look ok on our 27" bedroom TV. The set has been calibrated with Video Essentials, and the only other times I ever see this problem is when I watch a low quality VHS tape on it. Has anyone else had this problem with this TV and perhaps with "The Simpsons," and is there a fix for it? Thanks in advance for your help with this.
