I just registered for Amazon Unbox and I read in several places that the TiVo Series 3 is supported.
However, after linking my Amazon account with my TiVo account, only my Philips Series 1 DVR showed up.
So I went to TiVo Online | DVR Preferences and I saw that Enable Video Downloads is checked for my Series 1, but for my Series 3 it says “N/A”.
Now I know that Series 3 doesn’t yet support TiVoToGo, but I have never heard anything about not being able to download *to* a Series 3 or use Amazon Unbox – in fact, all the docs I’ve seen from both Amazon and TiVo seem to indicate that a Series 3 should work.
I posted on TiVo’s support forums and other folks also indicated that it should work.
I’m going to give TiVo a call and see what they can do…
In case you are still struggling … my Tivo3 worked fine except for Unbox, until I manually entered my DNS IP address. And magically, everything worked. Hope that helps.
