Is there any way to increase the number of theaters returned from using Avantgo? Currently it appears that I'm only getting theaters within a 5 or 10 mile range. I know that at the site you can select a larger radius (20, 30...), but there doesn't seem to be a way of doing this with the Avantgo channel. I tried using IsiloWeb, but that generated a file that was far too large and took way too long to convert/load.
