Actually the Humax Foxsat-HDR is no longer being made. HD is encrypted 
but there is Custom Firmware and a patch that enable you to access HD 
recordings without problem and do all sorts of other wonderful things. 
(For example, you can set up a  recording schedule using your PC or 
indeed a mobile phone - as I can access my home PC during my annual 4 
months in the Philippines I am able to organise recording schedules from 
over 7000 miles away!) AFAIK this isn't possible with any other Humax. I 
certainly wasn't aware of all this when I got it 6 years ago. I recently 
saw a Linux based quad-tuner PVR on the net and I guess when my Hummy 
dies, I'll have to look to something like that.

As the Humax records some programmes with two audio streams (the 
standard plus a Narrative stream), following Vangelis' advice I spent an 
hour or so this afternoon making sure that ffmpeg remuxes the correct 
audio stream. Lifelong learning! Great fun!
