Wintv DVB-T PCI Nova

[bakerboy26]

Hi All,

I have be trying to get this card to work in FC5 but I have no luck so far. It used to work in FC4 ok. In the KinfoCenter it says it is detected as a SAA7146 (rev 01) but I can't seem to use it.when I type in:

ls -l /dev/dvb/adapter0/
I get a error ls: /dev/dvb/adapter0/: No such file or directory

Anyone else had problems with this card?
How can I get this card to work?

Thanks in advance,

Gordy

Is your device showing up in lspci or dmesg?

$ /sbin/lspci
$ dmesg | more

Edit : use spacebar to scan ahead in "more", at the end it will exit.

ok I found the device using /sbin/lspci

here is what I get:

Did you see anything in the dmesg output?

For example, my lspci has my video capture card listed as :

00:08.0 Multimedia video controller: Conexant CX23880/1/2/3 PCI Video and Audio Decoder (rev 05)

...and if I dmesg and grep for CX238 I see :

 $ dmesg | grep 238
cx2388x v4l2 driver version 0.0.5 loaded
$ dmesg | grep v4l
cx2388x v4l2 driver version 0.0.5 loaded
cx88[0]/0: registered device video0 [v4l2]

Maybe if you grep for 714 or v4l you will see which device your kernel is assigning to it.

When you had it working on FC4 did you have to setup udev or upload the firmware to it? A lot of howtos talk about having to do such things.

hi John,

I get this:

[gordy@localhost ~]$ dmesg | grep 714
videodev: "SAA7146A" has no release callback. Please fix your driver for proper sysfs support, see http://lwn.net/Articles/36850/
saa7146: register extension 'budget_ci dvb

I tried /sbin/modprobe buget_ci dvb but does not return with anything. I also can't work out what device this SAA7146A is?

I also loaded the firmware. I did not need to do any of this in FC4 except change the permissions to the device as it would only work in root..

thanks for your help so far,

Gordy

Arrrgh. I can see in google that this driver is having problems in recent kernels. There are only two choices I can think of :

1) attempt to "yum update" the system. This might fix it.
2) try the "blacklist" edit as described at :

http://www.mythtv.org/wiki/index.php..._WinTV-Nexus-S

namely :

This chipset is also used by a video card. You will need to blacklist the stradis module from loading. i.e. With Fedora edit /etc/modprobe.d/blacklist and add a line "blacklist stradis"

The second choice is probably easier and faster than the first...you'll have to be root/administrator to do it.

In fact if you google for "blacklist stradis" you'll see you are not alone

hiya,

Thanks for your advice it worked with no problems this time. I had to edit /etc/modprobe.d/blacklist as you said and it worked fine. I also googled "blacklist stradis" i feel i have learned something from it all.

thanks once again,

Gordy

Great news, and you're welcome. Very strange problemo! I've not heard about blacklist before, good to know.
