Hi !
I want to build a digital multimedia system for my home based on mythtv
with a client/server architecture. Since i get my tv by cable (digital)
i have to use a (at least one) dvb card.

Been having some serious trouble in getting my dvb-card to work under
Fedora Core 3. Here is my setup:
Fedora Core 3, Kernel: 2.6.9-681_FC3
Hauppauge DVB-c premium card,CI and CAM (Hauppauge/Conax)
Using dvb drivers in kernel. udev/sysfs doesn't make devices so i use
the MAKEDEV-DVB.sh script from Linuxtv.
(btw. card works fine under windows)

lsmod gives:

dmesg output:

using dvb-apps/util/scan give me a channels.conf (i find almost every
channel...read somewhere that i should check some timeouts to get a
better scan result)

using same channels.conf as input for czap and i get:
[EMAIL PROTECTED] szap]$ ./czap -c channels.conf RTL -r
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'

FE_HAS_LOCK

(status tells me i got good signal, little noise and that there is data
on vdr0, trying to just do cat /dev/dvb/..../vdr0 gives output)

then i try to view the stream in mplayer and nothing happens...see below.

i've also tried xine and did not get a picture there either.
[mythtv]$ mplayer - < /dev/dvb/adapter0/dvr0

I have never tried piping the output from the dvb device straight into mplayer but is suspect it will not work. Try using dvbstream and pipe it's output to mplayer, this works for me:

dvbstream -o -ps -qam 64 512 650 1590 | mplayer -

you will of course need to substitute the appropriate pids for you station (use scan -c to get the list of available pids)

Cheers,
Mark

Hi there - just been through the DVB-T route on FC3 - one thing you must do is not use the MAKEDEV-DVB.sh script - as FC3 uses udev. Read the file udev.txt in the dvb-kernel cvs - /DOWNLOAD-DIR/dvb-cvs/dvb-kernel/linux/Documentation/dvb/udev.txt - that tells you how to setup udev to setup the device correct - otherwise it won't play fair.

Hope that helps,

Cheers,

Richie
