The delay is 0.10 sec between each code, it works perfectly for all other channel macro's on this digibox, i've tried duration at default 0.01 and in .10 increments up to .5 sec so far.

I've checked and double checked, the link is definately to the right code. I've been doing channel macro's for years now on my original RU940, RU970 and now my TSU7000 and I've encoutered problems before usually silly errors, but never anything like this.

I've run out of ideas to try,really frustrating.
