You probably need to reduce the delay between digits. Note that there is a
"delay" which controls the time between digits sent, and an "rdelay" which
I think is an additional delay if the digit is repeated (i.e., 1224 would
delay more between the "2" digits to avoid the cable box's debounce which
might exclude the second "2"). I use delay=0.2 and rdelay=0.2 for my cable
box and I haven't had a channel change failure since I made that change (a
year ago?). Previously my timing was too aggressive and it would sometimes
get the wrong channel. But I only have 3 digit channel numbers max...
