I too have a 3m dish set for circular only with a dual ortho an Cal Amp lnb's, an I can hit Intel-901 for my farest east sat.
now getting to Intel-707, I have No signal on the 3820-V TP, that you're asking about, but their is a sports channel on 3942-H on IS-707 that scans in as "Sports", don't know if it is Sports Max or not it comes in as scrambled right now, an from time to time is itc, an have not noticed if it is sports max or not have not sat an watched it, but real its a real hot signal here in Fla.
but 1 thing to take into consideration here tradewinds is the feed that I have an what pedragon is using, they are circular feed horns. as a matter of fact would luv to have a ADL feed but can not seem to spend $500 just for that feed only. if you are planing to get a lnb-f an put a die-ectric plate in it, they do not work very well at all, their is a lot of anntuation once that plate goes in the feed throat, an also their is a big trade off when converting a leniar feed over with a plate to circular, yes they do work, but not well, to where you may need a bigger dish, to get some of these signals.
now don't know what kind of sports that you are looking for but over to the east their is a lot of Euro sports feeds of all kinds that I find here, an bunches of soccer stuff.
