I thought the C61 used the tuners in the HR44, so I was surprised to see that both receivers tuned to the same music choice channel were not in sync. I changed the channel and changed it back just to ensure I was “live”. Have you noticed this? Is it closer in sync between different modes (HR54, HS17, etc)? Since it was on the same channel I would have thought the C61 would have tuned into the same stream (or tuner) for efficiency, this receiving the exact same bits.
