IPTV slow switch channel

Hi, i have rpi3 and kodi 16.1 and iptv list in .m3u with .ts links ( i can’t have others formats )

I don’t know why but change channel is always very slow, 10 seconds are a lot.

But if i use these builds from milhouse are too fast!

And these builds are based ( last build ) on Kodi 16.0 beta, not 16.1 stable version.

So i don’t understand how to have fast switch channel in stable version.

Can you provide to figure out?

Please i blow my mind for that.

Thanks for the support.
