Query: Will not play in my HD-DVD player

This title will not play in my Toshiba HD-XA2 DVD player. It locks up the player and I have to turn it off and back on to get the player to function again.If you know why this might be, please do let me know. All other HD-DVD titles and movies I've tried play fine (have not tried another Discovery Channel title though).
