I finally have things tweaked so that I barely miss any button presses any
more with my setup. I found that the most important thing was to use sudo
and nice to make the change channel script top priority. That way their is
not too much delay between digits being sent to the box.
I found in my logs that on the failed channel changes, their was often a 5
second delay between the first and second digits, thus the first digit was
I would try to change to channel 26 to watch Gundam Seed, but the 2 would be
lost and I would be stuck with half an hour of Leno on 6.
In mythtv-setup my change channel script is call thus:
sudo nice -n 15 /usr/local/tunetv2
where tunetv2 is my customized change channel script that uses the correct ir
blaster (I have 2).
Give this a try, it may work for you as well.
