The ONLY reason for that question is to make sure you have the right TV guide. It doesn't affect the streaming at all. And as the TV guide is supported only in USA & Canada it is irrelevant. Tell it you are in the USA, enter a valid ZIP guide (90210?) and then select 'My TV Provider is not listed' and you are good to go. I have been asking to Sling to add an 'Other' option for years now but as usual they ignore me.
