http://www.ontvtonight.com/guide/listings/AustinNight.html somehow already has GRIT and LAFF, just as www.TitanTV.com does. To be fair to Tablo, Huffington Post TV listing does NOT contain the new channels,. I just sent them a message.
Sadly no listing for my zip code…
I like Titan TV on my android phone, but I have always used zap2it on my desktop.
Nice, because you can login and customize it to the channels and mark the favorites you watch.
