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
