RadioX listen again - Couldn't create command line for mp4 playback

Hi All,

I wonder if anybody here can help me, I'm trying to open the listen again stream for Radio X.
I have taken the url (http://fs.geronimo.thisisglobal.com/...e50df8900f.mp4) from the page source of http://www.radiox.co.uk/london/radio...d-a5d02fe2f17c
When I try to play the mp4 on my Squeezebox Boom I get the following error in the squeeze box log.
[15-10-06 23:04:44.6291] Slim::Player::Song::open (409) Error: Couldn't create command line for mp4 playback for [http://fs.geronimo.thisisglobal.com/...50df8900f.mp4]

If I play the URL on my PC all works well.

If any one can shed any light on a fix to this it would be much appreciated.

Thanks

Alrighte
