[linux-dvb] libdvb and dvbscan
Hi all, I started hacking together a general-purpose DVB library. It can be downloaded at: http://jemmari.tky.hut.fi/dvb/libdvb.tar.gz It's very much work-in-progress at the moment, but I put it there so you can see what the API is going to be like. The package includes only one test program, ingeniously called 'dvbscan'. It will parse the PAT, SDT and PMT tables and print out all the services. At least here at the university campus it did. =) Your mileage may vary. In the future dvbscan will be able to scan through a number of frequencies, and output the channel list in various formats. You will have to specify your DVB driver include directory in Makefile for the package to compile correctly. A recent CVS version of the driver is required.

[linux-dvb] Patch for cards with the Philips CD1516 tuner box (spXXXX?)
I managed to get my Fujitsu-Siemens PCI-DVB Cable card to tune to the
whole frequency range (130..460 MHz) by patching the driver. The diff
against the latest CVS HEAD is attached.
I also cleaned up the tuner_set_tv_freq() function a bit.
Cheers,
Juha

I am Frightening! :) I was just about to write the list about the same problem.. I'm using Debian 3.0 with a Nova-t in the UK.. and I had everything working wonderfully a few days ago... I was installing some kernel header packages earlier today to try and get a Quicknet PhoneJACK working.. and once I was finished playing, to the best of my knowledge I undid all the installs / changes...

[linux-dvb] drivers for the B2C2 (eg. Technisat SkyStar2) card ready!
I don't know if you all know, that on 2002 March 22, B2C2 has released Linux drivers for their DVB cards. You can grab them in one of these places: http://www.oskom.ru/drivers/b2c2_install_base.tgz http://www.yansat.page.pl/programy/skystar2/b2c2_install_base.tgz http://www.esat.pl/files/dvb/technisat/b2c2_install_base.tgz They are precompiled modules for kernels: 2.4.2 2.4.2-2 2.4.3 2.4.7-10 2.4.8 2.4.9-13 2.4.10 2.4.17 I do not know what the -2 -10 -13 numbers mean.

[linux-dvb] DVB-T and RedHat 8.0
Hi,
I am having problems getting the dvb driver working on RedHat 8.0. I am
using the Hauppauge NOVA-t and previously had it working fine on RedHat
7.3 (using files obtained via the LinuxTV public CVS repository in early
September). When I installed the driver under 7.3, I followed the steps
outlined in this How-To posting -
www.linuxtv.org/mailinglists/linux-dvb/2002/01-2002/msg00246.html,
excluding the line 'make dep && make && make modules' in step 1.
The kernel I am using in RedHat 8.0 is 2.4.18-14 and I have the kernel
sources in /usr/src for that version also. The DVB driver I have was
obtained from the CVS today (13th Oct). The first problem I had was that
when I typed 'make' in the DVB/driver directory, an error appeared saying
that tmp_include_depends could not be found. I managed to fix this by
running the 'make dep...' line, mentioned above, in the linux kernel
source directory. 'make dep' seemed to work correctly but 'make' and 'make
modules' seemed to results in errors. Running 'make' in DVB/driver now
resulted in the driver compiling successfully. The problem I have now is
that 'make install' results in the following:
/usr/src/linux/scripts/pathdown.sh: line 4: TOPDIR: parameter null or not

You need to use the dvbtune program from http://www.linuxstb.org/dvbtune/dvbtune-0.3.tar.gz You will get an interface like dvb0_0, you will be able to see it in ifconfig. -- Miernik _ / / tel.: +48608233394 / / mailto:miernik@;ctnet.pl __/___/ ICQ UIN: 4004001 msg06576/pgp0.pgp Description: PGP signature
