TV question problems with audio interferance

[liner33]

Have a problem with my mums TV , if she is watching a DVD she can still hear the audio from her freeview box in the background

DVD and freeview are connected to the TV via scart leads

The is a standard aerial lead as the TV has a built in freeview reciever but if she unplugs the aerial the audio stops

Can you get filters or suchlike or any ideas how to fix??

It could be one of a numnber of things. A badly shielded Scart picking up the signal from the Aerial lead. Another is that the Freeview box passes though a signal on the Aerial for TV's that don't have a SCART socket. It will be using a Analogue Channel to do this. Retune the box away from the analogue channels on the TV. This usually only occurs on one channel though. Generally I'd switch the box off.
