Sorry it's taken so long to check this, I've been rather busy. Anyway finally 
got around to trying this on an EPIA. Firstly dumb question... do I need to 
apply this patch to the backend also (backend is current CVS)? I've got a few 
recordings scheduled and don't want to break them! :)

If the normal backend should be fine... then the patch breaks epia playback.
