I've been burning DVD's with DVD shrink for several months. Most of the time it works without a hitch. I watch the green bar and occasionally it has a red bar at the end of the green bar. This is rare and I know that means there's too much material for the blank disk. All I have to do is delete a few unnecessary things,the red bar disappears and it copies. Here's a new one I've never encountered. When it gets to the checking disk stage and I've inserted a blank disk, a window pops up which says, "not enough space to burn this compilation to this disc". I've made numerous attempts with other blank discs with the same result. If there wasn't enough space, why didn't the red show up at the end of the green bar? The original disk is 2 hrs. and 42 min. I've copied movies that were 3 hrs. long with no trouble. The disc is not encrypted. What's the problem?
