I've been using VDR for a long time with one DVB-C card. Now I've added a second, identical card (Technotrend DVB-C 2.1).
I get a picture,
Where do you get the picture? When connecting a TV on the second card or when recording and viewed via the first?
AFAIK VDR is supporting only one primary device.
but it's of very low quality and breaking up all the time.
Hmm. Ok. I've tried lots of different stuff now, but no change. Still unwatchable with two DVB-C cards in the machine. Tried to measure the signal strenght with the femon plugin, but I'm not really sure how to interpet that the signal-to-noise (SNR) ratio goes between ~87-91%.
that value should be OK. (I am running at STR resp. SNR as low as 65% with DVB-S)
If it is the signal strength, what do I do? Use the shortest possible cable? Buy an amplifier?
I've just taken the coax cable from the cable-tv wall outlet, plugged in the first card and then used a short coax cable and connected the two cards.
Have you swapped the the sequence: connect the wall outlet cable to the second card and then interconnect the first card to the second?
I looks very much that: The second card does not get enough signal(as i said: The cable signal is typically so low that not more than one receiver can be conneted), very annoying. So you need an amplifier.
Maybe an external splitter would be worth a test too, so both cards gets a lower level Maybe something like BVE 2-01 @ 2,90 Euro.
An amplifier like Axing TVS 10-00 37.90
might be too fat.
But don't by too cheap. The amplifier must be specified for "cable" else the signal quality may degrade.
But a
Axing TVS 8-01 16,90Euro TV distribution amplifier "suitable for CATV (TV, Radio)"
would be sufficient too. (See reichelt.de for a datasheet)
- Use the old card as second board
Check.
That means: If you use the old card as second card the receiptiton on the second card(=now old card) is still broken?
