Is there a difference between ATT's free HBO and the one that comes with my FIOS? I noticed that on my free HBO, I get HBO East HD, HBO Family and HBO Latino.  

On FIOS, I see HBO HD, HBO HD West, HBO2 HD, HBO2 HD West, HBO Signature HD, HBO Signature HD West, HBO Family HD, HBO Family HD West, HBO Comedy HD, HBO Comedy HD West, HBO Zone HD, HBO Zone HD West, HBO Latino and HBO Latino West.  

Are all those HBO channels just rehashes of the same thing?  I want to cancel my FIOS HBO and use the free one with my plan but it looks like I'll be missing out on several channels.
