No problem. As you saw on the sticker, the HD DVD will not play in a regular player. This high-definition disc will only play in an HD DVD player. It will not play in a standard-definition DVD player, Blu-ray player, or PS3.
I have not seen it but this is what Amazon says about it... Caroline (Kate Hudson), a hospice worker in New Orleans, becomes so disillusioned with her job that she answers an ad for a private in-home caregiver in a parish about an hour out of the city. Upon arrival, she meets Violet (Gena Rowlands), the wife of her new patient, Ben (John Hurt). Violet is reluctant to have strangers in her house, a large plantation home that has seen better days, but their lawyer, Luke (Peter Sarsgaard, "Kinsey") insists that she get help for Ben during his last days; he had a heart attack while working in the attic and is now paralyzed on both sides of his body, unable to speak or move. Caroline accepts the job and soon receives a skeleton key that will open every door in the house. Exploring the house, she soon makes her way up to the attic and begins to discover some strange things.
