Yes.  Use

alias char-major-81 videodev
alias char-major-81-0 ivtv

and nothing else...  And only:

/usr/bin/ivtvctl --device=/dev/video0 -f width=720,height=576
/usr/bin/ivtvctl --device=/dev/video0 --set-freq=10472

No need to set the video standard (-u) or the msp34xx IO mapping (-v).  
It's done for you.  Also, the video output defaults to both Composite 
and S-Video, so no need to set that.  The only things you have to change 
are those you should change--i.e. capture resolution and channel.

Try ivtvctl -h for more info.
