    If there is some means for you to validate what channel you've tuned
too (or not) then add that to your change script. I found I had to do that
with USB-serial control of one of my DTV boxes. Once I did that, it turned
out that I was having more tuning issues with my other box than I realized.

    Now my script does a loop of "change channel - check channel" rather
that just assuming all went well.
