Hi all, This is primarily aimed at a representative of HD Connectivity, possibly HDC Techie but I'll take advice from anyone... I received my hub about 3 weeks ago and have been mainly watching TV at the remote locations now that my previous issue seems to have resolved itself. However, now that I've been watching TV in the same room as the hub I've noticed that it emits a whistling sound which is probably from some kind of fan inside the unit. Is this normal? I ask the question because it's done this since I received it but it wasn't really noticeable until I started to spend more time in the same room as the hub. It's loud enough to be heard over the TV unless there's a noisy, action-packed scene playing and is detracting from my enjoyment of the otherwise excellent unit. Is there something I can do about this perhaps? Thank you, David.
