Does IPTV cause 'tune failed' on satellite box

Hi,

I have a DM800se which has the coaxial cable for sly freesat but also IPTV on there as well. Now normally the box works reasonably well minor all things considered, but what I have noticed from time to time is when I receive 'tune failed' that it appears to be linked to when I switch to an IPTV channel and then go back to a freesat channel and the picture then starts getting scrambled and the 'tune failed' becomes intermittent. If left alone on that freesat channel eventually it will work normally and switching to other freesat channels causes no issues, but as soon as I switch to a IPTV channel and then back to freesat more often than not I can see that that channel is about to say 'tune failed' or it becomes scrambled for a while.

Can using IPTV cause current interference that can effect a satellite box or freesat on the same device?
