Switched DVR outputs; can't find signal... Help?

[cwb]

I can import the DVR signal to my tuner card with this VLC command syntax:

v4l2-ctl -i 0

ivtv-tune -c3

vlc pvr:// :pvr-device="/dev/video0" :pvr-radio-device="/dev/radio0" :pvr-norm=0 :pvr-frequency=-1 :pvr-bitrate=-1

But now I've switched the TV1 and TV2 outputs from the DVR, and I'm lost; anybody know which value I need to change for the signal to properly tune?

Solved; set command string 2 to channel <whatever DVR channel 2 is set to for modulator setup>. Default was 60, but it had been set to 73...
