everything marked as NTSC on lyngsat is a analog channel. It can't be received with any DVB FTA receivers (well there was one that
Sadoun used to sell that could receive both, but that was awhile ago). You can buy analog receivers for pretty cheap on ebay.
Everything marked as F is Free To Air. Everything in gray and usually labeled as a "feed" is just that a feed. That means that occasionaly something might pop up there. IT is by no means a 24/7 signal and it will go days without anything on it and then maybe have a 15 minute usage by CNN or ABC or whoever leases that transponder.
If you want to watch feeds like that your cheapest bet is to buy a Blind Search receiver (like Lifetime Ultra that Sadoun sells) and you would just select that satellit and thell it to search for any active frequencies on it. It will give you even more stuff than what is listed on lyngsat.
