I am experiencing problems with the Humax occasionally freezing when I am accessing the Media screen at the same time as the Humax is recording. When this happens: recording stops (and when I later access the recording, the message "Recording failed: loss of power. Do you want to play this file?" is displayed) the Media screen continues to be displayed the Humax fails to respond to its buttons and to remote control The only way to re-start the Humax is to switch it off at the plug. Having read various posts, I am wondering if there is a problem either with the HDD or with the PSU, and am considering replacing the hard drive. But before I do that, I'd welcome any other observations or suggestions.
