Digital copy problems

[ThatWriter]

Hey All,

Every single Blu-ray I got over the holidays came with a digital download and every single one of those downloads won't transfer to my iPad. Okay, it works just fine on my computer through iTunes, but suddenly they just won't work on my iPad.

Stranger still is that every time I try to sync one of these digital downloads to my iPad, I get the same message: The 'Movie title here' was not copied to the iPad because you are not authorized for them on this computer.

The computer is authorized, always has been and suddenly, it stops working. Weird. I changed nothing on my computer or my iPad so, it's just baffling. The folks at Apple have tried to help but to no avail.

Have any of you had this problem? Any advice would be greatly appreciated. Thanks for reading.

Cheers,
Ian
