Keeps scanning for channels

Hi,

I’m using a Raspberry Pi 3 with Xbian installed. I use PVR IPTV Simple Client on it and it works great.
There’s just a couple of things that bug me.

For starters every time I reboot it will scan the “client list” and all the channels again before I see the TV section. I guess I could live with this since I don’t reboot it that often.

Another thing is that this can occur just random and it can just start scanning the client/channels again and the TV section disappears.
Sometimes this has happened when I’m switching through channels. It just goes dark and I get kicked out of the TV section and it disappears and starts to scan again.

This is really annoying and I’m wondering what’s happening here?

Is it my provider? Misconfiguration or what? Or is it suppose to be like this? It’s not really reliable to watch TV when it is like this and I’m just wondering if there’s anything I could do to fix it?
