I'm sorry if this has been answered before, but I couldn't find anything specific to this question.

Does anyone know...if you took advantage of the 3 free HD-DVD offer earlier this year, are you eligible for the 5 free offer Toshiba is offering right now?

I took advantage earlier with the HD-XA1, but I couldn't resist the recent deal on the HD-A2/Matrix offer at Amazon. Now, I'm starting to worry that Toshiba won't honor this newest deal since I already took advantage of the previous one.

I'm thinking they would be considered separate offers and I should be ok. But does any one know for certain?

You can always put it in someone else's name, or use another address.
