I am using Logitech Harmony universal remote control, and following happened a few times in the last 6 month or so since I got the unit -when watching TV (I have cable). 1. when pressing Volume DOWN button, volume goes UP. It happens so rarely that it is not a big deal, but I start to wonder why.. 2. sometimes after I press volume button the AVR would change VIDEO input ONLY to AV - everything else (audio and HQ video) remains set to SAT. This one is confusing for my family - they cannot see the picture and unable to figure out why. SInce it happens so rarely I do not think it would make sense to use original Arcam remote so I could replicate the error. I wonder if anyone had same/similar problem and what was the solution if any. Thanks for any info.
