I began my evening watching U-571 on HD-DVD. I bought this for $4 many, many months before the Blu-ray was released, but I've always found it to be a wonderful edge-of-your-seat action film. Superb transfer and, of course, the sound was state-of-the-art then, and it still holds up very well today. All those depth charges going on all around you, and the windows in my den were shaking.
