I suppose that maybe owners of the EH50 and ES20D might be able to shed some light on this question for me too. This is a UK specification DMR-EH60D that I am talking about, by the way. I have noticed that when in standby, or with the hard drive in "HDD Sleep" mode, the machine gets rather hot. It's particularly noticeable around the rear right corner of the top (above the RF in/out connectors) and towards the centre front of the. It's quite a bit cooler over the DVD drive area. Heat's hard to gauge subjectively - all I can say is that it's hot to the touch, even to a warm/hot hand - not enough to burn you but at the "blimey, that's really quite hot!" level - I suppose similar to the heat on top of a typical CRT display that's been running a long time, or an LCD monitor's screen that has been running quite a while. It cools down rapidly when the machine is on and recording or playing, because then the fan runs and within minutes it's comfortably cool all over. But the fan NEVER runs in standby or with the HDD in sleep. Is this normal? Panasonic's helpline was a bit vague (well, it is a new model I suppose), saying be cautious and keep an eye on it. The recorder's in a sufficiently-ventilated position - nothing blocking the air intakes and exits, anyway. Any opinions would be much valued, thanks.
