Hi guys. Many thanks for the input here. Just to clarify I am not recording, just playing music (mp3) off the hard drive via media centre. I would say that this happens very often, on the odd occasion it will work fine. It seems the longer the music has been played the more likely it will return "tune fail" upon exiting.
Typical of the English my grasp of other languages is very poor. However on-line translators are usually useful, providing the article is not written technical?

Thanks

Ray
