Using your login details this script can grab the m3u8 links from the USTVNOW website. It's nothing fancy, I made it because the current scripts out there don't work! And I wanted to watch American TV via an IPTV client rather than via a website or addon. Running this script with print out the video links.
Usage:
Grab only the free channels:
python main.py [username] [password] free
Grab all channels:
python main.py [username] [password] all
Enjoy :)
