this is the script I use on my parents MythTV setup with two HD-PVR's:

-------------------------------------------------------------------------------------------------------------------
#!/bin/bash
#

GUID=`echo "$1"|sed -r "s/[A-Z]+/\L&/g"`
CHANNEL=$2

6200ch -v -g $GUID $CHANNEL
sleep 3
exit 0
-------------------------------------------------------------------------------------------------------------------

in the command line setup I give it the path and the GUID, ie
/usr/local/bin/hdpvrchanger.sh 0025F2FFFEDA1379
the channel is added to the end by MythTV

adjust your sleep value based on how long it takes your STB to change
and lock channels
