Guided Setup on Roamio question

Hey all,



I have looked for an answer to this but haven't found any.



We currently use DirecTv. But we have had it with them. We are looking into getting the basic Tivo Roamio (over the air and Internet services) but can't seem to find out if the guide info will include all the TV stations we currently have over the air using the DirecTv HR-20.



See, we live mid way between Chicago, IL and Milwaukee, WI.



The bottom line question is: will the guide info provide info from both markets? The only info I have found is that the Tivo guided setup will ask for my zip code. The DirecTv setup asks for both the zip codes for my home and a second zip code which I enter a zip code from Chicago.



But nothing is said whether or not the guide merely uses the results from the automatic channel scan. My antenna picks up all the stations in both Milwaukee and Chicago and I don't want to lose that. Any ideas?



Also, what is the current list of Internet services provided on the Tivo Roamio? Looking at the Tivo web site doesn't appear to provide that info either.



We appreciate the help.



Cheers
