Hi!
I'm using LibreELEC 9.0.2 on a Raspberry Pi 3 with a 1000baseT link. I connect to a tvheadend 4.2.8 server on a FreeBSD box. I recently updated the hardware on the box. Now HTSP connections for recordings via the Tvheadend add-on (pvr.hts 4.4.18.1) are constantly buffering. The weird thing is that it only happens to recordings and only on the PI. Another client on an iPad works fine. Live TV works fine, Samba connections from the pi to the same box works fine. It worked a few days ago, so I kinda think it is related to the hardware change, but because everything else is working well (or even better than before) I don't think it is a hardware issue.
I'm at a loss how to fix or even debug this.
