Mike,

That's actually a good point - do you have any real-world figures for
your PCI DVB-T tuners (how many/model/power usage when
idle/recording)?

I've not yet bought an inline power usage meter, but it might make for
a useful set of figures if MythTV users with inline meters contribute
their tuner/capture card (and overall system) power consumption
figures. It could go a long way to building lower power HTPCs based on
real-world numbers.

Cheers,
Nick
