spoke too soon.  i still think the channel number is not being passed to the script:

 [11:40am]# cat change_channel
#!/bin/sh
/usr/local/bin/6200ch -v -g 001xxxxxxxxxxxx -d 10 -4 $1
/usr/local/bin/6200ch -v -g 001xxxxxxxxxxxx -e
sleep 2

and the log:
2010-06-20 11:38:29.278 TVRec(1): HW Tuner: 1->1
Usage: 6200ch [-v] [-s] [-w] [-m] [-e] [-4] [-n NODE] [-g GUID] [-p PORT] [-d DELAY] <channel_num>
-v        print additional verbose output
-s        use single packet method. Cannot be used with -4.
-w        toggle power state
-m        Sends "Menu" command.  Needed for some Motorola QIP series STB's.
-e        Sends "Exit" command.  Needed for some Motorola QIP series STB's.
-4        Enable 4 digit channel number support. Cannot be used with -s.
-d        inter-digit delay in ms (default 500)  Cannot be used with -s.
-n NODE   node to start device scanning on (default:1)
-p PORT   port/adapter to use              (default:0)
-g GUID   GUID to use, -n switch, if present, will be ignored.

i can see the exit command being passed but not the channel number.
