I bet if you do a tracert on that, you will find alot more hops with your's compared to your neighbor's.
I also bet that if you setup your own server host and direct traffic to there and then from there to iptv server (and vise a versa), then it would work.
I am pretty sure that this issue is how your traffic is handled by your ISP, the URL is not being resolved correctly and after much ado it finally sees the URL but looses the packets because of the 'much ado' thing
Just a theory
Go back to your command prompt and ping the server again. Look at the bottom of the results for packet loose information.
By the way, tracert is done same way thru that command prompt as is the ping option is performed.
Just type 'tracert' instead of 'ping'
