I was going to buy the 300 HD-DVD/DVD combo disk from Amazon.com http://www.amazon.com/gp/product/B000Q6GXW2/ref=amb_link_7111472_1?pf_rd_m=ATVPDKIKX0DER&pf_rd _s=asin-coop-gp-1-A&pf_rd_r=0RS7GWP358RBN84K3840&pf_rd_t=101&pf_rd_p =412564401&pf_rd_i=193642011 and I just wondered if the normal DVD side of the disk is region locked, as I know the HD-DVD side isn't.

I live in New Zealand, so if the DVD side is anything other than Region 4, I won't be able to play it.
