[QUOTE="Vipersan, post: 1007581, member: 325666"] Thanks for looking buddy .. I do hope you turn up something suitable. Afaik ...CD and DVD use different wavelengths of light ..and very often you can encounter a situation where a player can read a cd ..but fails to even recognise a DVD disc .. From this I can only conclude there may in fact be more than one diode lazing at the focus . So I doubt it is the same optical unit.. Take for example CD which produces visible red light (not that you would ever look at it directly) ..whereas Bluray by definition uses a blue lazer light .. rgds VS [/QUOTE]
