KWorld DVB-S 100 satellite tuner card on Fedora Core 6 ?

[m0dY]

Hello,

I'm trying to get my "KWorld DVB-S 100" satellite tuner card to work on Fedora Core 6.

After searching the forums and googling a bit i found that i should be having a /dev/dvb dir which in my case is not existing.

Here's is some helpful output from my system.

Although all of that, the first time i tried to install "Kaffeine" it told me that there isn't any DVB cards found so it's modules won't load.

Anyone with an old experience with that would be helpful :) .

,Thanks.

I don't know much about dvb devices but I did find this wiki when looking for compatible cards.

I have the DVB-t 100

I had some trouble with it loading the wrong modules. Can you do an lsmod please?

[loodpool]

your dmesg says :
cx88[0]/0: registered device vbi0
so you have to look after /dev/vbi0 and not /dev/dvb

you have a CX23880 based card and there's no module in /lib/modules/2.6.20-1.2933.fc6/kernel/drivers/media/dvb/frontends
my ls says:
ls /lib/modules/2.6.20-1.2933.fc6/kernel/drivers/media/dvb/frontends/
bcm3510.ko dib3000mb.ko dvb-pll.ko lnbp21.ko nxt6000.ko sp887x.ko tda10086.ko ves1x93.ko
cx22700.ko dib3000mc.ko isl6421.ko mt2060.ko or51132.ko stv0297.ko tda8083.ko zl10353.ko
cx22702.ko dib7000m.ko l64781.ko mt312.ko or51211.ko stv0299.ko tda826x.ko
cx24110.ko dib7000p.ko lgdt330x.ko mt352.ko s5h1420.ko tda10021.ko tua6100.ko
cx24123.ko dibx000_common.ko lgh06xf.ko nxt200x.ko sp8870.ko tda1004x.ko ves1820.ko

so I don't think you'll get your card works and you have to build your card driver if there's one provided by the manufacturer.

I didn't think cx23880 was the frontend?

As I said, I have the kworld dvb-t 100 and had a couple of little hiccups with fedora auto-configuring the right modules. Once I sorted that out by loading the right module, it was fine.

[JonC]

Also, can you dmesg | grep DVB to find out which frontend is being used. My DVB-T is a Zarlink, and that was the cause of the trouble.

Thanks for holding up,

here's the output you wanted.

$dmesg|grep DVB
CORE cx88[0]: subsystem: 17de:08b2, board: KWorld DVB-S 100 [card=39,insmod option]


glad i found someone having the same doomed card :) .


,Thanks.

[JonC]

Well, mine isn't exactly the same - it's a dvb-T

can you also post the result of:

dmesg | grep frontend

and maybe lsmod ?

[m0dY]

$dmesg|grep frontend
DVB: registering frontend 0 (Conexant CX24123/CX24109)...

Well,

Looks like the new updated version of kaffeine detected the doomed card :)

Thanks for trying to help

,Thanks.

[JonC]

great, glad you got it sorted!

Now you can get MythTV (http://www.mythtv.org/) going!
