The problem with the Raspberry Pi 3

Hello everybody!
Bought Raspberry Pi 3. Took to view IPTV
Put Openelec latest version.
And then there were problems. Many of the bands in the canals.

With that, when you turn on these channels are working properly, then leaf through the channels, and go back and strip again.

I Tried:
– OpenELEC Stable Releases (6.0.3)
– OpenELEC Beta Releases (7.0 beta 3)
– OpenELEC Legacy Releases (5.0.8)
– LibreELEC-RPi2.arm-7.90.006
– AlexELEC-RPi2-2.18-20160717
In the first two the same problem, the third does not start at all.
The fourth was not observed this but in the full screen picture is late.
a problem similar to the first C AlexELEC.

In general, it did not try, it’s not that.
With that, on Windows Kodi all ok on Raspberry Pi 3 such problems.

Please tell me, the problem in hardware or in software. By the end of the order left a couple of days, so please help with this problem, and you do not want to throw money away.

And in general, whether the Raspberry Pi 3 for watching IPTV?
Or is it better to buy some some other device?
Thanks again!)
