DVB Card support in LinuxMCE-0710

[totallymaxed]

Andrew,

I'd like to see support for the Twinhan budget cards..
VP 1020, VP1022, VP 102C, etc (I have them all)

Regards,

Dan

I hope this is in right topic!

I have a Twinhan DTV Mini Cab (w/o CI) DVB-C card.
The card is working to see tv channels, but if a want to scan for channels whit it, it don't find anything.
To get this working i need to uncoment line 1360 in kernel-<version>/drivers/media/dvb/bt8xx/dst.c that reads

Code: [Select]

!(state->dst_type == DST_TYPE_IS_CABLE) &&

and then make new kernel.
I have tried to do this in LinuxMCE the Ubuntu way, but i allways fail when it reboots the new kernel. To get it up and running again i need to reinstall LinuxMCE...

The question i have is:
How do i compile kernel for LinuxMCE whit this "fix" and get it working?

Thanx
/Mami

Hmmm... I would think that you just need to re-build the bt8xx module with the dst_type set to Cable and then modprobe the newly built bt8xx module. If it modprobe's ok the just edit /etc/modules and add a line for your new bt8xx module. Your new module will then get loaded on boot.

I think that should fix your problem

All the best

I have tried whit to modprobe the bt8xx module whit many dst_type, but nothing worked (a long time ago!).
Then i started to search the net and find that answer, and it worked directly.
Because else it think it has a CI onboard or something like that!!

Edit:
I find this text about it:

Code: [Select]

There are exactly 2 card types having the same identification, adding support
for this one card breaks the other card.

Edit2:
Finaly i got it working 
So if you have a Twinhan DVB budget card whitout CI that can't scan for channels, do this:

1. Download kernel source + needed packages!

2. Edit this lines in drivers/media/dvb/bt8xx/dst.c (in the kernel source):
Line: 850:

Code: [Select]

.dst_feature =  DST_TYPE_HAS_CA,
change to

Code: [Select]

.dst_feature =  0,

and in line 1360:

Code: [Select]

!(state->dst_type == DST_TYPE_IS_CABLE) &&
change to

Code: [Select]

// !(state->dst_type == DST_TYPE_IS_CABLE) &&

3. copy config from /boot/ to .config

Code: [Select]

cp /boot/config-<version> .config

4. Apply config & prepare

Code: [Select]

make oldconfig && make prepare

5. build the drivers

Code: [Select]

make M=drivers/media/dvb/bt8xx/

6. copy them to the kernel you use

Code: [Select]

cp drivers/media/dvb/bt8xx/*.ko /lib/modules/<version>/kernel/drivers/media/dvb/bt8xx/

7. Reboot and have fun

Hi,
Just wondering whether DVB-S2 card support has been integrated into 0710?
I'm hoping to use VDR with a Hauppauge Nova-HD-S2 card.

Cheers

[cirion]

LMCE 0710 is using the latest stable version of VDR, which is version 1.6.
VDR removed DVB-S2 support for this version to be able to release a new stable version.

DVB-S2 is back in VDR 1.7 but that is not a stable version, so it is not in LinuxMCE yet...

Your card needs to be supported in the Multiproto driver to work with DVB-S2. Look for your card here:
http://www.linuxtv.org/wiki/index.php/Main_Page

As long as you install a driver for your card, DVB-S should work fine for now. DVB-S2 will come eventually...

[gazlang]

The card is supported under the "experimental" section of DVB-S2 PCI cards. To get the card working with only S functionality for the time being do I just have to install the v4l dvb drivers without patching them etc.. as mentioned here -

http://ph.ubuntuforums.com/showthread.php?s=78b0b299797591a3233c9ed93f954361&t=633182&page=3

I assume this is still needed for the S2 element to work.

[cirion]

I'm afraid it's not just the DVB-S2 support that is experimental...
The card itself has experimental support, so there is no support for it in the std. v4l dvb package.

Did you not read about your card?
"Hauppauge WinTV-NOVA-HD-S2 (PCI32, supports CI) ... a HVR-4000 without a DVB-T demod"
What that means, is you can follow the instructions for HVR-4000...
http://www.linuxtv.org/wiki/index.php/Hauppauge_WinTV-HVR-4000
and here is the driver:
http://dev.kewl.org/hauppauge/

Since your card is "multi frontend" DVB-S and DVB-S2 ther will be some time before v4l dvb will support your card. The HVR-4000 card came out in the end of 2006 and is still not supported.

There is sad news for the above driver... If you look at the VDR 1.7 changelog, you will see that it will only work with the Multiproto driver...

[gazlang]

Well, I will just have to play around with it. I assume the kewl.org driver will allow me to use the DVB-S part of the card with LMCE VDR (v.1.6) for the time being?

From this wiki entry - http://66.102.9.104/translate_c?hl=en&sl=de&u=http://www.linuxtv.org/wiki/index.php/Hauppauge_WinTV-HVR-4000 it seems that there is a multipronto patch for the 1.7 versions of vdr. So should be able to continue using my card when LMCE upgrades to VDR1.7?

[nite_man]

I use TT-Budget/WinTV-NOVA-CI PCI. It works fine out the box. Just disable the "snd_aw2" (Audiowerk sound card) module. The driver contains a bug, so it will be loaded for every saa7146 chip.

I thought to switch to Technotrend S2-3200 HDTV-S2. But since support of DVB-S2 was removed from the VDR 1.6.0 it'd be just a wast a time and money.

Hi Andrew,

Very nice to see this topic up!
I'm having a go at Satelco-EasyWatch-HDTV-S2-PCI--Basic-Edition[/color]-.html]http://www.dvbshop.net/product_info.php/info/p148_Satelco-EasyWatch-HDTV-S2-PCI--Basic-Edition-.html.
I have it running in one system but am having trouble in getting it going in an identical second system.
It is a Philips SAA7146 based card.
One of the problems, probably similar to Niteman's post is that part of it gets recognized as a Audiowerk2 audio card, and next sound isn't working anymore... But after blacklisting this item that is solved.

This is what's in dmesg in the working system:

Code: [Select]

[ 14.324000] saa7146: register extension 'budget_av'.
[ 14.324000] ACPI: PCI Interrupt 0000:03:06.0[A] -> GSI 20 (level, low) -> IRQ 21

And this is what I get in the non working system - apparently the DVB-C card doesn't get registered

I also have a Technisat HD2 Cablestar HD2 reported to be working under Kubuntu 8.04 http://www.linuxtv.org/wiki/index.php/Te…t_CableStar_HD2
I haven't managed to get it working with LMCE, but will have another go at it and report back.

Does anyone have a clue as to how to get my card registered by the system?

Thanks for your input!

Erwin

As you can see in the LinuxTV Wiki the Philips SAA7146 based cards are all experimental:
http://linuxtv.org/wiki/index.php/DVB-S2_PCI_Cards

If you enter the Satelco cards you don't really find any useful information either...

You could follow this wiki, that is for a similar card:
http://linuxtv.org/wiki/index.php/DVB-S2_PCI_Cards

WARNING! If you are using LMCE7.10RC2 do not waste time trying the v4l-dvb/S2API driver. It will work as a driver, and you will be able to scan, but there is no support for S2API in the current Mythtv or VDR versions, and there is no patch for S2API in the versions LMCE is using.

In the same wiki you will find the Multiproto driver, and this uses the old API that works in LMCE.
 Multiproto driver

A driver using the obsolete multiproto API may be installed as follows.

Installing on Debian (2.6.18-6-686) etch with Multiproto diver (!!!DVB-S2 Don`t Work. Only DVB-S!!!). Install new Debian (2.6.18-6-686)

hello
i still don't have my LMCE working (in the year)
but i am not agree with :

there is no support for S2API in the current Mythtv or VDR versions

VDR 1.7.x works with S2API
VDR 1.6.x just need a patch to works with S2API
bye

Since LinuxMCE includes "stock" version of VDR it shouldn't be a problem

GREAT!!! You don't agree that it does not work with S2API.
That means you actually know how to make S2API work in LMCE7.10RC2?!?

Please tell us how! I want to know! I have been waiting for this since Steven started talking about S2API...

[tityann]

hello

That means you actually know how to make S2API work in LMCE7.10RC2?!?

I don't know about it...I only say that VDR is ok with S2API.
I still don't have my future house (with autamation) and still don't use LMCE (don't have two network...)
but why couldn't be add the S2API to the LMCE 7.10 's kernel ?
from linuxtv :(what i have done in my current install)

To retrieve the v4l-dvb source tree:

hg clone http://linuxtv.org/hg/v4l-dvb


How to build the v4l-dvb kernel modules
The v4l-dvb tree is backwards compatable against recent vanilla kernels. Kernel version 2.6.10 or later is required to build the dvb modules, and version 2.6.12 or later is required to build support for hybrid devices.

Change into the v4l-dvb directory:
cd v4l-dvb

Build the modules:
make

Install the modules:
make install

and then only change in the Makefile of vdr
DVBDIR=/usr/linux/
(which is using the dvb from installed kernel
to
DVBDIR=/usr/linux/v4l-dvb
(the new modules S2API)
(if you put it there of course)

How did you read that S2API can't be installed in 710?!?
It CAN!
And YES! The driver works!!!

The problem does not lie there.... It's in VDR and MythTV and in LMCE7.10, they are specialized versions. Figuring out how to set up a development environment and patch and build new versions of MythTV or VDR for LMCE, is not something I would recommend to a  user wondering how to install a DVB Card.

VDR and MythTV does not support S2API in any stable version yet, and both the stable versions and the developer versions needs to be patched. Patching scare the shit out of any Windows user trying to use Linux for the first time and is something regular linux user don't find very simple.

S2API will probably make it into 8.10 (I'm just guessing). Posde has commented somewhere that the new VDR integration would be able to use whatever VDR version the user installs. If that's true it would make users able to install the latest developer versions with patches
