Hi,
recording to the NAS and watching afterwards works fine with no frame drops. Only watching directly is the problem ... maybe I have to look if there is some transcoding or similar ongoing ...
I don't have the MPEG license, however German DVB-T2 is h.265 / HEVC ... and it is only the tvheadend backend running on the Pi, not the frontend displaying the video ... so I would assume the license should not really be the issue.
