I'm having trouble with the picture quality on my Sony 34XBR960 when using a VCR. I'm normally good at troubleshooting problems, but this one has me completely stumped. I hope someone here has a suggestion that might help. Shortly after purchasing the Sony HDTV, I noticed an intermittent blurring/ghosting of the picture when I would play back tapes made on my VCR (at that time a JVC HR-VP59) through the composite input. The picture would blur slightly for just a split second. It didn't seem to happen with any regularity and didn't repeat on a consistent basis. Sometimes it could be fine for an hour, while other times it could happen every second or two. I thought there was a problem with the VCR, so I bought a new JVC HR-S3912 and connected it through the S-Video input. The problem still continued. Interestingly enough, I found that prerecorded tapes and tapes made before the purchase of the HDTV played back fine! I also took some of the tapes I had trouble with to a friend's house and tried playing them on his system. Of course, they played fine there. My guess then was that there had to be some kind of interference problem, so I upgraded all of my cables and played with every hookup combination I could think of. The problem remains. So now I'm at a total loss. Any ideas?
