The home screen on my Google TV does the same thing (huge ad for the Sixers game, smaller box for Phillies on Apple) but that only works if you have subscriptions (I do have Apple, I don't typically have Prime). But yeah with YTTV you no longer need to know the channel numbers or even what network the Phillies are on (NBC Philly, one of their alternates, FS1, Fox)... as long as they are on.
Also spoiled by YouTube multiview though NBC Sports Philly isn't friendly to that anyway.
