I'm on Necro right now and it's good with no interruptions....however their bitrate is not the highest I've seen. I was on a free trial with a very cheap chinese provider from evybuy and the bitrate was even higher.

There's also iptvthebest, but they don't have any US channel so for me they are off the list, but you might check them out as well.

I'm also looking for a good provider with Italian, US and UK channels (if they can throw in Indian, Spanish and Asians that's a plus).

All the providers I tried are not doing good with Italian channels, they end up having problems, constant buffering and so on. Any good advice?

We have a HUGE Selection of ITALIAN VOD Moves and TV Shows, updated weekly.Also all the other Italian channels ofcourse. Check the channel list here http://themasteriptv.com/channel-list/
