[mythtv-users] Problems viewing TV

It seems it was my ivtv drivers failing to load properly. After reading this thread:
I modified my modprobe.conf as follows (noting the PAL vs NTSC differences):
# ivtv modules setup
alias char-major-81 videodev
alias char-major-81-0 ivtv
alias char-major-81-224 ivtv
alias char-major-81-1 bttv
alias char-major-81-225 bttv
options bttv tuner=2 card=70 radio=1
install ivtv /sbin/modprobe --ignore-install tuner && /sbin/modprobe --ignore-install msp3400 && /sbin/modprobe --ignore-install videodev && /sbin/modprobe --ignore-install saa7115 && /sbin/modprobe --ignore-install saa7127 && /sbin/modprobe --ignore-install ivtv && /usr/bin/ivtvctl -d /dev/video0 -u 0xff
install bttv /sbin/modprobe ivtv && /sbin/modprobe --ignore-install bttv && /sbin/modprobe --ignore-install bt878
Now, when it works (see below) I can define either card alone, and it can be used to
watch live TV, or define both and it uses the first defined (I presume if it were busy recording
it would fall over to the other, but haven't tested it).
The only problem I have now is that when mythbackend starts at boot, if I load
mythfrontend and select TV, I get an error about /dev/dsp being in use. I can
then watch TV with no sound. However, if I drop to a shell and restart mythbackend,
I no longer have whatever conflict there was with /dev/dsp and it works just fine.
