Thanks for the reply. The CD audio player docs don't mention CD-Rs at all so I have emailed Hitachi for an answer. In the meantime tried burning another very cheap CD-R Brand (Tevion) and it plays on the Hitachi and all my other CD players.

Original discs I tried were HP CD-R C4437A (not TDK as I previously stated). I thought HP were better quality and therefore more likely to play but it seems the cheaper discs do the trick.

Only other thought is I did something incorrect on my first attempts however I don't recall doing anything different.
