PROBLEM w/ cx88-dvb and WinTV NOVA-S-PLUS
« on: December 03, 2008, 07:24:58 pm »
I've spent alot of time trying to setup the NOVA-S-PLUS DVB-S card on a default installation of LMCE according to a post on here that card should be 100% compatible with LMCE; but it won't work.  Basically it seems to detect everything on the card except dvb.  So I end up with /dev/video0 but no /dev/dvb.

According to : http://forum.linuxmce.org/index.php?topic=3785.0

The card should work perfectly; but the cx88-dvb driver will not load.  Please help, I don't want to return to Windows

You can install the latest drivers from linuxtv.org. The steps to do it are here but are a bit general, so can be hard to understand.
http://www.linuxtv.org/wiki/index.php/How_to_build_from_Mercurial

First from a terminal session (from KDE desktop, System-Konsole)
Code: [Select]
sudo apt-get install mercurial
Then follow the Retrieve and Build steps.  I think you can ignore the rest of the page.  You *might* have to retrieve the "kernel-headers" package, can't remember if it is installed by default with LMCE.
Code: [Select]
sudo apt-get install kernel-headers
If your kernel has the module you need built into it, there is an additional step to "blacklist" the existing module to let the new one get loaded.

Code: [Select]
nano /etc/default/linux-restricted-modules-common

Disable the kernel module DISABLED_MODULES line to read:
Code: [Select]
DISABLED_MODULES="cx88-dvb other_driver1_ other_driver2"

Other_driver1 and other_driver2 would be other module names that relate to your DVB-S card.

Also worth looking in the mythtv.org wiki http://www.mythtv.org/wiki/index.php/Hauppauge_WinTV_Nova-S_Plus_PCI  and the linuxtv.org DVB wiki http://www.linuxtv.org/wiki/index.php/DVB-S_Devices for help

Good luck!

You can run "lsmod" to get info on loaded modules.  "sudo modinfo cx88-dvb" for info about the loaded module.

does dmesg show any messages about the card?  you can also try "view /var/log/messages"

Also, you can try to load the module manually.  You may be able to find out if there are any other modules that need to be loaded as well by looking at the web sites in my previous post.
Code: [Select]
modprobe cx88-dvb

well, I found out that the driver may not support the "demod" of this particular model.  I'm not sure if this is correct or not because after I came this conclusion I installed Windows and found out the card was not working there either.  Upon further investigation I realized that there was "burnlike" marks on the board so I am in the process of sending the card back for a new one.  Once I recieve a new card I will give it anther shot and post the results.

Thanks indulis for your reply
