This sounds like a misconfiguration of your MythTV video 
source/channels/input connections.  Since for external channel change 
scripts, MythTV simply sends the channel's frequency ID and the channel 
change script uses that information to select the channel to tune 
(usually uses it directly by sending a signal that includes the value 
received--i.e. uses frequency ID as the STB's "channel number"), if your 
system is tuning the wrong channel, you probably have the wrong channel 
in your video source.

However, I have no clue what "directv.pl" is or how it works, so I can't 
say for sure.

If it is an input connections misconfiguration, I recommend the video 
sources portion of
