Looking right now:
#80 is MASN2 2017 XTERRA Pan Am etc.
#580 is TCN WORX GT - 3 tools in 1
#578 is MASN MLB Baseball Red Sox Nationals
(I assume replay and I assume MASN is MASN#1))
Sometimes when I look at the guide #80 shows a Baltimore or Washington baseball game but when I select it the screen says it's YES [Yankee Network] and is not one of my subscribed channels.
