[linux-dvb] Help needed: No video/audio on Haupp. DVB-C premium 2.1 using FC3 kernel 2.6.9 (-681_FC3)

["Örjan Nordlund" <orjan@laxfiske.se>]

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:

videodev 13377 1 saa7146_vv
ttpci_eeprom 6465 1 dvb_ttpci

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

dmesg output:
DVB: registering new adapter (Technotrend/Hauppauge PCI rev2.1).
DVB: AV7111(0) - firm f0240009, rtsl b0250018, vid 71010068, app

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

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

sent the question to mythtv-users and got a suggestion to try 1)
dvbstream instead of czap and 2) use udev/sysfs for device creation
instead.


Tried the tips regarding dvbstream instead of czap, however the
problem remains. mplayer reports playing from stdin and still nothing
happens.
Tried to get udev to create my devices (even patched up udev from
fedora that should fix the dvb-problem). However, no matter how much
i try i can not get udev to create the devices properly. I've tried
different solutions but reading through posts from others I've
created:
/etc/udev/scripts/dvb.sh
edited /etc/udev/permissions.d/50-udev.permissions (added dvb section)
edited /etc/udev/rules.d/dvb.rules (and tried renaming it to
06-dvb.rules)
no errors in /var/log/messages
no devices ;(

now I'm in the dark and I do not know enough about linux to find more
errors. All HW reports OK (except for this message in log:
videodev: "av7110" has no release callback. Please fix your driver for
proper sysfs support, see http://lwn.net/Articles/36850/) I expect
this to be one of the reasons why udev won't create the devices.

As of now scan works. czap -r outputs some sort of data on
/dev/dvb/adapter0/vdr0 but I do not know enough linux to check the
format of the stream.

Anyone had a similar problem? I would really appreciate any help i
could get.

br,
Örjan
