The main difference between version 1 and 2:
main - some tricks for speedup starttime udp/http streams (mpeg2, 5-8sec);
support udp://,http://,rtp://, rtmp:// streams;
Channels logo in thumbnail mode for russian,ukraine named channels
(target audience was originally for the countries of the former USSR, because looks like here iptv more in demand and many providers include this)
or manually assigned logo (via list.txt "channelname->logourl")
TVProgram for ukr,rus channels (using WDTVExt plugin and Eject button for show prog, and some else)
Support some http iptv providers like
baton tv ( good choice for emigrants

)
ADDITIONAL CONTENT - many eng.,ital, esp channels in HD quality, see above (it seems that the temporary - I am not provider so don't know how long it can be used for free).
User always can go back to 1 version if don't need v2 futures. iptvv2 by default work in demo mode have nagscreen "demo". all can try and even use with nagscreen if has nerves of steel .. or can remove "demo" after small donation. Why? Cos for example iptvv1 was downloaded 5408 times .. and have donation from 5 peoples.. Looks like not very fair

Think for yourself, decide for yourself. Peace.
