I somehow missed the posts about AVRs changing the source input. I posted about this when I got my Onkyo and did a lot digging on the net about it. It seems to be a known "feature" of ACR that drives a lot of people crazy, especially those using activities on a Harmony, though it only seems to happen when first turning the TV on and doesn't seem to be limited to Samsung TVs. I turned ARC/Anynet off and am using a optical cable because of it.
