Tvheadend

Good, if you can guide me:

I have the Digibit R1 (with the alternative firmware: minisatip8) in a Libreelec I have installed the TVHeadend and Oscam, all the connections by 1G Ethernet cable, the case is that when playing the channels in HD (encrypted and not encrypted) I have cuts continuous and pixelations, this does not happen with SD channels. The client I use is VLC and tested in several devices: computer, tablet, mobile. I have also tried it from the browser. The fact is that I do not know what to do, if you can give me a little hand, a greeting!
