[mythtv-users] Way to change channel (setchannel doesn't work)

I am hoping someone can help me.  I have written an external channel
change script that does the following:

1) If the freqid passed in is less that 100 it treats it as a
terrestrial channel and tries to change the channel on the device using
'v4lctl -c /dev/video0 setchannel $1'
2) Else sets channel to the channel my Sky+ RF is on and executes a
channel changer command for my Sky control box.

Trouble is the setchannel doesn't work - I just get a burst of white
then snow!

It works fine through MythTV if I remove the external channel change
command (through setup).  If I try and use xawtv it moans about DGA -
though I did get it working with the '-remote' option but you still
couldn't change channels using setchannel.

I don't know what command MythTV uses to change the channel (as it
works!) any ideas? - Thanks.
