e.g. Despite Sony being a regarded name I recently tried
a DVD recorder from them. It had a cooling fan that was
so loud that it was distracting when listening to
dialogue on items recorded. This is absurd and needless,
yet when I asked a local Sony center their reaction was
'they all do it'. They seemed not to think it was a
problem, and clearly had no idea that quiet fans can be
bought. Perhaps they think everyone is too busy looking
at the pictures to notice the sound of a helicopter
accompanying it. ;-


I find no logic to the noise levels of DVD recorders. I have a
Philips/Magnavox at home that is as quiet as a mouse (no fan) and a Philips
at church I bought a few months later that has a fan and is noisy. I just
bought a RCA with a hard drive in addition to the DVD burner, and it is
smaller, cooler, and has no fan.
