It's Tuesday which means it's time for the Engadget HD Podcast. We hope you'll join us live when the Engadget HD podcast starts recording at 8:45PM. The big cable merger news finally got all official and we'll brake down why it will, or won't, be approved by Uncle Sam. There's more Chromecast news too and yet another Apple TV rumor -- we never missed an opportunity to poke fun at those. And of course there is other top HD news we'll go over as well. If you'll be joining us, take a peek at the topics after the break -- then do everything else you'll need to do in order to be ready to participate in the live chat.
