It seems to effect some people and not others. I do not know if it is really a function of the particular IR code or not, or if it is learned code or part of the database codes.
It happens to me rarely and some folks seem to get it frequently. The one thing that seems to make a difference is in how you press the buttons. A "complete" press almost always seems to work without repeating. What I mean by this is a press which is sustained for a brief spilt-second. Some shorter presses seem to cause the repeat.
You might consider getting new codes for your volume up and down if you learned them. See if other vol + and - act better, from the database.
Last but not least...people who created their config in 1.0 have reported excellent results by completely re-doing the config (not borrowing anything!) from the earlier config.
