The article New technology could end DVD format war was posted on Cnet this afternoon.

The article talks about how the British company New Medium Enterprises has figured out a way to produce a multiple-layer DVD containing both the Blue-Ray and HD-DVD version of a movie. There are two primary advantages to this:
1. Cost. It currently costs $.06 to produce a single layer DVD. Using NME's technology, the cost to produce a multiple layer DVD (they've successfully tested 10 layers thus far) is only $.09.
2. Compatibility. Consumers can purchase one copy of a movie that contains both formats, meaning that their movie library will not be obsolete depending on which format wins out.
