IPTV works in the USA and is legal as long as your IPTV provider has bought suitable licenses for the streaming content and is not violating copyright laws.  In other words, your IPTV service provider needs to hold legal licenses or have the copyright owner's permission to provide streams of copyrighted films, TV programs, and other content. In the USA, IPTV works great with Perfect Player and is, in fact, the most favored IPTV player.
