It is not Blue-ray. In fact, many of us have been misspelling it. It's not even Blu-Ray, it's Blu-ray (R not capitalized).\
As for your Price Grabber link, that's a misspell. Here's the product page at Phillips. http://www.consumer.philips.com/cons...37_US_CONSUMER
For your link at NexTag, you searched Blue Ray Players, and Blu-ray players came up. because Blue-Ray is a common misspell. Notice that all the products are listed as Blu-ray, not Blue-Ray.
For your JYI link, a journalist spelling it as Blue-Ray, doesn't make it right.
