playing mp4 files downloaded with getiplayere on my blu player

[chris chery]

i have asked  the question before  but i ve gotnowhere
 My blu player philips bdp 2500 will play the  avc video but not the audio 
aac of the mp4 files downloaded with get_iplayer
is there anyway I can keep the avc video signal( as any conversion would 
lead to a drop in picture quality) and convert the aac audio to something 
else (MP3 etc) and get it to play?
 thanks everybody
