Games get rebroadcast ~4 times before they reach your market.
Tip: go to the source (local market feed) or check the FanDuel channels — FanDuel often owns the broadcasts.
Sports seasons bring new channel categories.
Keep an eye on the channel list — NCAAF and NFL show up around season start. Yes, every single game.
Multi-view on a big TV: 2 streams is the sweet spot.
Adding a 4th stream increases timeouts. All-HD increases timeouts too — mix one in SD and one in HD, and use software encoding to help. During football or basketball season you can add a second subscription so you have two playlists (one per subscription) with multi-view on a larger TV — works like a champ.
