    HI guys n gals.... me and my mate are having a debate at the moment about dual layer drives on the MBP 'cos i am going to be ordering a MBP asap 'cos i just cant wait any longer for merom otherwise i wont have a computer for Uni.

    Basicly my mate reckons that dual layer discs can be burnt on both sides??? i have no idea how they work as ive never used or seen one he reckons that they do this and that if i got the 15" MBP i could just turn the dvd round once it had burnt on one side and then do the otherside??:confused: i thought it was just a dual "interface" (probably wrong word) on one side...

    so whos right 'cos it would help me have another reason to get the 17"MBP

    oh and does anyone know what power the speakers are on MBP's ie what Watt are they??

    thanks people,

    Ste

    the dual layer dvd burners encode two layers on ONE side of the disc. you have to have the dual layer discs for it to work as well, but it can also burn regular cd/dvds too. the dual layer discs do cost more, which is the only downside really.

    no problem. oh and to find the wattage of the speakers it might be best to go to apple.com/hardware and find the tech-specs, might be listed there.

    ehh, you're more right than your friend is.. dual layer means two data surfaces on the *same side*. to confuse things, however, there are dual layers discs which are also double-sided, so that you can record two layers on one side, flip it and record two layers on the other side. the two surfaces are written/read by changing the focus of the laser

    that's a strange question to ask. a speaker can be rated in terms of how many watts it can safely handle, but given that the amplifier is built-in to the MBP, its not like you need to worry about overpowering the speakers. are you simply interested in how loud they can be? if that's your real question i have no idea. those figures are likely not published by apple.
