I hope by exposing some of the dumb mistakes I have made, that it may help someone else. I found that I was having interference at the beginning of my movie, bright pixel type squares would flash around. It drove me crazy for weeks trying to figure out what was causing it. I discovered that I had set DVD Shrink to read at 32KB Blocks while Nero was set to read at 64KB Blocks. Both Nero and DVD Shrink must both be set the same. As soon as I changed DVD Shrink to the default 64KB Blocks that took care of my problem. Here is a hint, once you have found the cure to your problem, you can take the movie that has the interference on it...re-copy it and you will get a good copy with no interference. The interference does not transfer to the new copy. Cool huh? I will keep posting as I make more stupid mistakes!!
