so, i finally got my tv-card working.
I get video signal on both tuners, and can change the channels. everything seems
to be fine, but:
i can't change the channel without loosing sound, this means. the first time i
fire up mplayer to watch /dev/video0 or video1 i have sound (same in mythtv)
but as soon i want to change a channel (with ptune.pl or in mythtv) the sound
is gone. and it doesnt come back until i remove the modules and modprobe them
again.

i've made a /etc/modules.d/ivtv and it looks like this:

alias char-major-81 videodev
alias char-major-81-0 ivtv
alias char-major-81-1 ivtv
options ivtv tda9887=0,0 ivtv_std=2,2


the dmesg output after loading the ivtv modules:

so I don't get any errors at all. could anyone help me with this?
