I know I have read the answer in a forum but used the search and can not find it. That's why I am asking this question (again?) I've been playing around with the PIP on my 435 HDE. But as a result in normal mode, when I push the P+ button, I will go from channel 1 immediately to 4 !!!! and then to 5,6,7 etc... so it skips 2 and 3. 2 and 3 are still part of the favorites and I can pick them by pushing that channel. But zapping is no longer possible. Anyone had the same experience and came up with a solution ?
