See Sascha Prüter's reply towards the bottom of the post. In the demo you can see Live Channels running one of the tuners.
Holy crap this is amazing. No need for cable. No need for subscriptions. Heck, no need for HD homerun. This is all you need.
This is going to be great for a lot of people. Can't help but wonder how many though. My cable subscription only costs me a few dollars bundled with my internet bill and provides me a whole lot more than I could get ota so my hdhomerun/cablecard aren't going anywhere for now.
It'd be nice if I could take the pretty-much-useless ATM Haupage tuner I bought for my XBone under the foolish presumption that M$ was actually going to deliver on its long-promised DVR functionality and plug it into my SHIELD.
If done correctly, this will be a cordcutters dream, simplified. No messing around with WMC, Media portal or another pc back end. You will be able to buy an antenna, hook it up to your USB tuner, plug the USB tuner in, and use the live channels app to record OTA tv.
My tablo might end up being for sale next year.
