Lag on IPTV Stream

[Tunes0710]

Hi all,
On my IPTV stream, I seem to get a brief pause.. it happens at random intervals of between 5 and 10 seconds... it's only a brief pause, but it's noticable.
I have Kodi and NextPVR running on the same box, have xTeve handling the m3u in to nextpvr.
First of all I thought it was because of xTeve, so removed that from the equation and added the m3u direct in to nextpvr.
Then I wondered if it was Kodi, but the issue also happens watching a channel through the NextPVR web interface.
However if I use an IPTV app on my phone/android box (such is IPTV Smarters), the playback is absolutely fine.

Is there any special logging you need me to do, which can help fault find?

Is it all your channels or just some channels? I found that with my IPTV provider, US based channels keep up just fine, but some of the others are bit more stop/starty. (I see the same thing in other players)

If we need to, I could try one of your channels here to take a closer at how it's behaving

It's strange... it was all channels.. then it was just all US channels... now it just seems to be sporadic ones, which would indicate either an issue with the IPTV provider or my internet.
But I don't get why it doesn't buffer/lag/jitter on my phone using an app with XC login, as it uses the same internet connection.
