Questions about setting up service with Comcast Cable

Apologies if this is the wrong forum to post this in...



We're buying a house and setting up our cable service and I am trying to make sure that we get everything set up to work with the Tivos correctly. We have two Series 2 units.



Question 1: Is there anything I need to know about setting up Comcast with my Tivos?



Question 2: Some of their packages include a "high-def box". Will I need any special equipment to make this work with our Tivos?



Question 3: One of the packages that Comcast has offered me includes their HD DVR, which I don't think we need, but it is somewhat attractive as it includes all the premium channels... The sales rep I spoke to said it would still work with our Tivo as it would function just like a high-def box. Is this true? Is there any issue I need to be aware of?





Thanks for any help guys!
