Purchased a 1913 about a week ago and set it up last weekend. It all seemed to go pretty smoothly including the latest firmware update. However, I noticed that the Favorites menu seems to only work sporadically. I can't seem to scroll through them properly. It just hangs on Favorite 1. Also, it seems that occasionally while listening to Pandora, when it changes to the next song, I will get no volume/sound. When it switches to the next song, the sound comes back. Really like the receiver but these issues are scaring me. I have not reset the microprocessor yet - hate to lose all of my settings. Is anyone else having (or had) these issues and what did you do to resolve them? Thanks.
