Technisat Cablestar HD2 , No input detected / Too bad signal quality

Added by jaiz edelmann over 13 years ago

Okay, so i have a big issue with my tvheadend / tvcard. I've been strugling to get everything up and running but its running now or well it was. I add'd my providers main MUX which then add's addtional muxes and ultimately ends up in beeing channels view able from tvheadend/xbmc. Now that worked for like 20 minutes then it lost signal, and now after a reboot or two, i keep getting errors:

"No input detected"
"Too bad signal quality"

Now i've testet the same cable that goes into the pc and that is not the problem, so the problem must lay around the tvcard, i can also see in tvheadend that the signal strenght on the mux's are terrible.

Is there something i'm missing?

I compiled latest V4L driver by following this guide: http://linuxtv.org/wiki/index.php/Te..._CableStar_HD2.

Do i need to find some sort of tuner adjustment app? or something?

Running on: Lucid Minimal installation (2.6.32-32-generic) , Technisat Cablestar HD2 , Tvheadend 2.12.99

Update: some of the mux's are now in the green but still not perfecct, some of the channels are viewable however the screen is just gray with crackled sound

I had the exact same thing with the same card. Very bad signal appeared to be the issue of the distorted image and sound.
Then I decided to put the same card in a Dell Vostro 200 machine -> all perfect! Same Ubuntu OS, same Tvheadend version, etc.

So I have
- system A: Intel DQ57TM with Core i5-650 - NOT OK: bad signal resulting in loads of "continuity counter error"
- system B: Dell Vostro 200 with Core2Duo - OK

All with the same:
- cables
- OS - both Ubuntu Lucid (+ v4l compiling) and Natty
- Tvheadend version
- Muxes config
- IRQ sharing

Now I am lost in what can cause this issue. I am certain it is something hardware-ish like a slightly different power on the PCI bus, grounding issues, etc.

Note: my TV connected through the card, no problem at all; stable signal there.
