Any suggestions for custom activity buttons for this HD-PVR on Harmony One?

How about delays and repeats? Whats the lowest you can get away with?

If you are asking to be able to change the Icons for the Activity buttons on your Harmony, the answer is no those can not be changed. As far as delays there is no easy answer to that, as delays are based on your devices and combination of devices in an Activity what delay setting may be good for you may not be good for someone else. If you are having problems, you will have to try different settings based on your type of problem.

I have never had to tinker with either delays or repeats on my VIP622 nor any other Dish Receiver. The defaults have always worked right out of the box for Dish products.
