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:

lspci gives:
02:03.0 Multimedia controller: Philips Semiconductors SAA7146 (rev 01)

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:
[mythtv at localhost szap]$ ./czap -c channels.conf RTL -r
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'

status 1f | signal ffff | snr efef | ber 009ffff6 | unc 00000000 |

(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.

after about a couple of minutes the following text appears:

All tips and tricks are highly appreciated. I'm kind of stuck at the
moment and do not know how to move this closer to a solution.

Please help a recently converted M$$ to Linux-noob.

Best regards,
Örjan Nordlund
