Version of TVHeadend: version 4.2.8-34~g24a2f59e9 Running on what OS and version: Raspbian GNU/Linux 10 (buster) Package that came with the OS or something...

What's your signal strength like?

Sometimes you'll find USB devices require more signal strength to work reliably than a TV does.

tilo Stadi

Thanks for your quick answer!

As far as I know, the signal strength is excellent:

Which is quite normal because it's a dvb-c tuner, I don't use a small internal antenna but the wall antenna plug.

EDIT : and I just tested to plug this same dvb usb key, connected to the same antenna, directly to my laptop. Now it's perfectly working, no freeze nor artifact.

So it seems to be linked to my raspberry pi setup.

Any idea?

"[425280.400909] usb 1-1.1.3: dvb_usb_v2: will pass the complete MPEG2 transport stream to the software demuxer"

Does your pi have an MPEG2 license?

tilo Stadi

I haven't.
But these tv streams are in H264, not in MPEG2 right?
"H264 @ #420 Continuity counter error (total 289)"

Hiro Protagonist

Yeah, if it's H264 you should be good.

Have you checked if there is updated firmware for the tuner?

tilo Stadi

There is not.
As I said earlier, the same tuner is perfectly working on my laptop. Which is also running debian buster.

So I guess the problem is somewhere else than in the tuner.

Any idea?

Is LNA enabled?

tilo Stadi

I assume not, according to line 5:

{ "rootpath": "/dev/dvb/adapter0", "frontends": { "DVB-T #0": { "lna": false, "pids_max": 32, "pids_use_all": true, "powersave": false, "tune_repeats": 0, "skip_bytes": 0, "ibuf_size": 188000, "status_period": 1000, "old_status": false, "enabled": false, "priority": 0, "spriority": 0, "displayname": "Realtek RTL2832 (DVB-T) #0 : DVB-T #0", "ota_epg": true, "initscan": true, "idlescan": true, "free_weight": 0, "remove_scrambled": false, "networks": [ ], "linked": "", "type": "DVB-T", "uuid": "8ae0da8f7c739bae71753082a2c9ee30" } }, "ca_devices": { } }

Should I change something?

I have heard that Raspberry Pis can struggle if their power supply is insufficient.

Je76 what OS you use? You have a lot of USB devices ... maybe this is exacerbating the problem.
