Dvb-t
 
Hello all,

I am trying to get a DVB-T Digital Television card to work in my PC running Ubuntu 6.10 (Edgy Eft).

The card is a Tevion DVBT220, which essentially is a rebranded Kworld DVBT220RF card.

When I use the command 'lspci', the following line indicates that Linux can see the card in the PCI slot and identifies that the card has a Phillips SAA7133 chipset.

Code:
02:02.0 Multimedia controller: Philips Semiconductors SAA7133/SAA7135 Video Broadcast Decoder (rev d0)
When I use the command 'lsmod', I see the following line which I think must be relevant to the DVB-T card:

Code:
videodev                9728  1 saa7134

When I use the command 'dmesg', I see this section of relevence to the DVB-T card:

Code:

I have dvb-utils installed and when I use the command 'scan au_Sydney_Kings_Cross > channels.conf' I get the error:

Code:
scanning au-Sydney_Kings_Cross
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
main:2247: FATAL: failed to open '/dev/dvb/adapter0/frontend0': 2 No such file or directory
I was hoping if anyone could identify what the problem is and point me in the right direction for a fix.

Regards,
Greenie

http://linuxtv.org/wiki/index.php/KWorld_DVB-T_220 -- it seems you have to use newer code for this which is probably not in your kernel source.

http://linuxtv.org/wiki/index.php/How_to_install_DVB might be worth a look too.

Yes, I installed mercurial, the linux-headers and the build-essential packages using apt-get:

Code:
apt-get install mercurial linux-headers-$(uname -r) build-essential
followed by;

Code:
hg clone http://linuxtv.org/hg/v4l-dvb
Which downloaded a whole heap of stuff, then I changed directory to where the above downloaded to, then I did;

Code:
sudo make
then

Code:
sudo make install
then a reboot.

After rebooting I was able to:

Code:
scan <initial channels source file> > channels.conf
which gave me a channels.conf which I copied to /home/<user>/.xine and also to /home/<user>/.mplayer

Then I did:

Code:
mplayer -quiet -stop-xscreensaver dvb://"channelname"
Which resulted in successful viewing of DVB-T in mplayer.

However I cannot get good success in Xine, I can get video but no audio in Xine. Does anybody have any ideas on the Xine problem?
