What you mean? "So it seems from the thread that too often checks for information kills picture." ?

Hi Prog - thanks for an answer.

I just rephrased what user: racerua wrote earlier in this post.
"Due to hardware limitation, accessing RF status(power or quality) may interrupt streaming through USB. As for no issues with TVR - it reads RF status only during tuning or poor stream reception."

TVR seems stupid and it seems to me that it just takes picture and sound from USB tuner.
racerua also (probably) proved that with Tvheadend where he disabled that check picture improved.
Program like ProgDVB is advanced and smart and collects all the data and stats and signal strength so it seems like he might be right here.

In addition I can mention that this Astrometa is built in this device I bought: https://www.lechpol.pl/pl/product/23303 ... hevc-rebel
I read here that this chip is quite old however In Poland there are lots brand new devices like that and people buy it (in couple months we will switch to only DVB-T2 standard so I guess this device might even grow in popularity)

Seems to be too often. When I had 1 sec interval check in Tvheadend I had video problems. That setting was by default. I have not tried any other intervals, but used suggested advice to disable check. Disabling it solved the issue and now everything is smooth when using that software.

Off topic, sorry, but just wanted to say, thank you for this!
I am using the same usb dongle, just bought it recently, to attempt to record my TV but it was full of artefacts, jumping, continuity errors, unwatchable. The audio was proper.

Device: Astrometa DVB-T2 / Sony CXD2837ER DVB-T/T2/C
System: Debian PC
tvheadend: in docker

Most places where I looked just pointed to "signal issue", "power issue", but cable change or powered hub change did not help at all.
However adjusting my tvheadend settings by increasing status period like you suggested, completely fixed the issue.

How I changed it: configuration / DVB Inputs / TV Adapters -> View Level: Advanced -> Status period (ms) changed from 1000 to 60000.

So thank you for reporting your experience it helped me out today a ton!
