I found some practical Elgato EyeTV advice on the 123macmini.com forums. Although I actually haven’t experienced any of the problems mentioned in the discussion, I did a couple of changes.
One: change the 2GB hard disk live TV buffer to a 200MB RAM buffer instead. I don’t think it is that useful to be able to backtrack live TV and I’d rather spare the hard disk. Although I might change my mind. The record from Live TV buffer feature might come handy one day.
Two: tweak the power saving settings a bit. From now on, I’ll try not to put the mini to sleep manually and let it go to sleep by itself when there are scheduled recordings.
And as a bonus tip, I found out that you can put your Mac to sleep by pressing and holding the play/pause button on the Apple remote.
