[MPlayer-users] Playing trouble with multi-tuner dvb card

[Dominique Michel]

Hi list! I am an old linux user that have some trouble with my TV card
and mplayer. It is a Hauppauge WinTV HVR-4000-HD. It have 4 tuners:
radio, analog TV, dvb-t and dvb-s.

mplayer is installed from yesterday's svn. That on a gentoo ~amd64
system.

The analog TV seam to work fine (My antenna is not adapted for this but
I can see the snow and when the channels are changing). The radio is
working fine with mplayer. It is the only one player that let my to
listen to the radio without to use a cable between the radio and the
sound cards. Thank's a lot for that! The dvb-s and dvb-t are working
fine with kaffeine-0.8.8. (My wm is fvwm and I run jack all the time as
sound server, so kaffeine for kde4 is just unusable for me, no sound!
what a mess that phonon thing!)

I done 2 channels.conf files: ~/.mplayer/channels.conf.sat and
~/.mplayer/channels.conf.ter

lspci -v

The devices for this card are all in /dev/dvb/adapter0:
# ls /dev/dvb/adapter0
demux0  demux1  dvr0  dvr1  frontend0  frontend1  net0  net1

and it is no other adapter in /dev/dvb/

"mplayer dvb://1@" is working fine. I can watch the dvb-s channels.

But "mplayer dvb://2@" fail:

mplayer -v dvb://2@

If I move the channels.conf.sat and rename channels.conf.ter into
channels.conf, and run "mplayer dvb://", I get the same result.

After googling a lot, I find that the device order is hard-coded into
mplayer. I done some udev rules:

file /etc/udev/rules.d/10-local.rules
KERNEL=="dvb0.demux1", SUBSYSTEM=="dvb", ATTRS{device}=="0x8802",
SYMLINK+="dvb/adapter1/demux0" 
KERNEL=="dvb0.dvr1", SUBSYSTEM=="dvb", ATTRS{device}=="0x8802",
SYMLINK+="dvb/adapter1/dvr0" 
KERNEL=="dvb0.frontend1", SUBSYSTEM=="dvb", ATTRS{device}=="0x8802",
SYMLINK+="dvb/adapter1/frontend0"
KERNEL=="dvb0.net1", SUBSYSTEM=="dvb", ATTRS{device}=="0x8802",
SYMLINK+="dvb/adapter1/net0"

And ran "udevadmin trigger"
Now, I am able to watch both the channels from dvb-s and from the
dvb-t tuners with "mplayer dvb://1@" and "mplayer dvb://2@".

I think that writing udev rules is behind the capabilities of many
users. So, are you aware of this issue? and do you have any plan in
order to solve this into mplayer?
