With one exception all the programmes recorded satisfactorily with good Accurate Recording functionality (as has been the case for about 20 recordings on BBC and ITV during the last week). The one exception was Casualty which produced results I've never experienced before. The recording was of the correct duration with correct picture. However, there was no dialogue sound, just occasional commentary voice over describing the action. I'm guessing this is some sort of facility for disabled "viewers" but if it is I don't understand the value of it. If it was an aid for the partially sighted then surely they would want the dialogue? If it was an aid to those with poor hearing then the audio commentary would be of little value to them.
Does anyone know what this is all about.? And more to the point why did my T816 produce a recording in this form and has anyone experienced anything similar.

This is Audio Description (AD), a low bit rate mono audio channel which is broadcast alongside the standard audio, for the poor sighted. Some boxes record both channels, selectable in the audio prefs on playback, but always one or the other, instead of blending the two together as it should.
There's only one box I've heard of that makes proper use of it, and that was the Netgem iPlayer, for which the software patch that enabled it was an optional payed for extra.
It looks like your box has somehow managed to flip the 2 channels about. If you still have the recording, you may be able to change the audio channel on playback to get the normal audio. But if it's like my Daewoo, it doesn't record both channels.
