Where you probably have no channel 1 in your subscription, and the IR 
receiver on the STB likely received the 1, but didn't receive the 0, so 
it acted as if you had tried to change to channel 1--which doesn't 
exist--so it took you to the "closest" (or next highest or ...) channel 
that is a part of your subscription, so you got channel 3.

I suggest increasing the sleep time in your channel change script.  Is 
it set to 0.4s?  If so, try increasing it to 0.6 or 0.8 or even 1.

Also, make sure you increase the capture cards's signal 
and--especially--tuning timeout sufficiently to handle the longest 
sequence of codes you will be sending in the channel change script * 
sleep_time + a little extra.
