Hi everyone,
First post so please be gentle :-)
I was wondering if anyone can help me please - I am trying to get a
DVB-S PCI card working with Linux (Ubuntu 9.04). So far I can get the
card recognised by Linux, but it won't tune - Kaffeine does tell me
that there is 95% signal and 80% SNR, and I am using the same
frequencies etc that a standard Sky box uses.
The card is very common on eBay so I am sure there are plenty people
who have tried this / would want this working.
Some details that I hope will help someone who knows more than I do
about this!
The card is one of these:

Have tried plenty. Nothing locks./
I'm using the latest liplianin drivers - did a mercurial checkout and
build today:
$ modinfo dm1105

Have also tried the latest v4l-dvb drivers and get exactly the same
tuning problems.
Finally, dvbtune appears to say I have signal but cannot lock:
$ sudo dvbtune -f 1177800 -s 27500 -p v -m -tone 1 -vvvvvvvvvvv

So I am thinking that this could be a driver issue? If the card has
good signal and SNR in Kaffeine, and dvbtune says it has signal and
carrier - but cannot lock?
Please can someone help me debug this?
Thanks a lot!
Shaun
i have a few and they work fine
in my small little way i helped to get them to work
in fact i tried to import a bulk shipment from china - but they offered
the same price for 200 as i can get on ebay - so i didn't bother
are you sure the signal is good? have you tried with another card to check?
