The tv app on the M8 is loads better than watch on, on my S4. Better range as well. It pulls all the channels from direct tv.. kinda like the Netflix layout. The volume rockers control volume on tv and you don't have to move from the attached screenshot to select channels. So, you can go to a particular channel and not have to " go back" to continue browsing...I'm actually using this. Every time I think this device couldn't get better, something pops out lol. Love it.
