Can anyone confirm if the US version of this will play in a Region B player?

In the database it is shown as no region coding and I wanted to check before buying it.

Thanks.

I have a feeling that it will be encoded for region A only. New Line opted not to release the HD DVD version until 2008 because of the lack of region coding for that format:

New Line Home Entertainment will set holiday style Nov. 20, when it releases Hairspray in three standard DVD versions and on Blu-ray Disc, the studio’s first high-definition release.

The dual-format supporting studio also will release the musical on HD DVD, but not until the first half of 2008 due to the format's lack of regional coding, making the title a de facto Blu-ray exclusive in the fourth quarter.

So it seems unlikely that they would release the Blu-ray region free...
