While watching programs, we can hear a voice describing what is happening. This sometimes means that we cannot hear what is being said by the actors. The voice over is also heard on the recordings.
I would appreciate any help. It has only started in the last couple of months
Turn off Audio dialogue - Don't know your unit but think there must be a button on the remote perhaps "AD"?
Audio Description - (on remote 3 up from bottom 1 right (next to opt+)). It has a speaker icon with a ? mark next to it. Press again to remove the AD icon so you see just English.
Someone will no doubt have pushed the button accidentally (do you have a cat ? 
)
AD works slightly differently to Freesat on HD channels. (Repassac lives in France). On freesat the AD track is a separate audio track to the main Dolby Digital audio. On Freeview-HD the AD data is embedded in the same audio track (It uses aac audio that is capable of including AD in the same data0

AFAIK with Freeview HD and SD transmissions, the AD audio is still contained in a separate stream to the main audio stream. Only difference to Freesat is that both streams are in AAC format. Main audio uses AAC, whereas AD uses HE-AAC, which is only suitable for lower bit rates.
Copying a Dragons Den Episode (which has AD), I will let you know. Never seen more than a single track on other recordings I have transferred (Could be a coincidence that none had AD).
Here's MediaInfo for an episode of Coast I recorded on my HDR Fox T2
