i suspect there's a minority market all iptv developers are missing,
no sports|porn, but instead you get every english language stream
from all over the world, so besides the usual us ca uk nz au streams
get all their cabletv/satellite channels even if they seem redundant,
as the same cabletv channel will have different programs by country.
you include 24/7's music & news streams geared to english speakers
who visit countries all over the world, plus good english VoD libraries.
leave out english network local market stations - those are just stupid,
all you need is a us east and us west coast version of every ota network.
The trick is to find a service that's both cheap & reliable that offers M3U, then use another service like iptv-epg to whittle it down to only English channels. I have less than 100 channels in my entire list with Eternal ($5 a month). Anything more than $10 for a service, and I prob wouldn't even bother. I don't care about sports, vod, catchup or anything like that.
