DVD-RW?

I have just downloaded the Jaguar 10.2 preview video from osrumors.com...and have a quick question...



I haven't as yet used a superdrive equiped mac (although my next power mac will be, when apple pull their fingers out!), but was under the idea that it was not a DVD-RW system....merely a DVD-R and CD-RW combined drive...



However in the 'disk copy' video at exactly 1 minute 15 seconds, one of the menus clearly states as an option "Erase CD/DVD-RW Disc"



Just wondering if anyone knows if this a normal menu option on Superdirve macs, or an indication as to a DVD-RW superdrive 2??

    I checked my Disck Copy utility, and didn't see that command - but I haven't seen the video you're talking about, so I don't know for sure.



    But the Pioneer drive Apple uses does have DVD-RW capabilities, Apple just hasn't implemented the software side. So it does not mean a new SuperDrive. By the way, the SuperDrive in the new iMac is a new version of the Superdrive, and it does have faster DVD rewrite speed.

    iMac:

    ? SuperDrive (combination DVD-R/CD-RW drive; writes DVD-R discs at 2x speed, reads DVDs at 6x speed, writes CD-R discs at 8x speed, writes CD-RW discs at 4x speed, reads CDs at 24x speed,)



    Powermac:

    ? SuperDrive (combination DVD-R/CD-RW drive; writes DVD-R discs at 2x, reads DVDs at 4x, writes CD-R discs at 8x, writes CD-RW discs at 4x, reads CDs at 24x)



    Wow. It reads DVD's at 6x instead of 4x. So THIS is the blazing new Superdrive II. Wonder why apple didnt make a huge deal about it

    interesting thing about dvd-rom reading speads



    my iMac DVSE has 4x dvd-rom

    my friends athlon 1600xp has a 16x dvd-rom



    guess which one skips



    his computer has 512 megs of ddr-ram

    he has 120 gig HD

    1.4 ghz AMD athlon

    basically he has a top o the line PC

    and it was hardcore skipping and wasn't very in synce(a/v) while playing the Victor wooten live at bass day '98 dvd, which I jstu got wednesday and have watched twice so far



    isn't that ridiculus?

    it also takes a long time to open up folders

    and if he leaves his computer on for too long it gets INCREDIBLY slow(way slower than my dinky little 500 mhz DVSE)

    Sorry about the link, didn't have time earlier on...



    <a href="http://www.macrumors.com/"; target="_blank">Macrumors...</a>



    The video is linked from the current first story about X.2 'Jaguar'...



    I believe it is also now at Spymac.com, (however it looks genuine this time !)



    The precise video I'm talking about is called "disk_copy.mov", and the DVD-RW reference is 1 min 15 secs through...



    Hope this helps,



    Marcus

    I'm not sure, but I think that the SuperDrive can read and write and rewrite DVD-RWs as well. Not DVD-RAMs, nor DVD-R+ or whatever it is called. It can rewrite one of the versions of the competing DVDs tandards,

    It can't do DVD-RAM and DVD+RW (stupid panasonic!)

    But it can do DVD-RW which has a bettter chance of being able to be played in set-top-box DVD players...

    The real reason for the new superdrive isn't the 2x dvd read speed boost (although i think it's a nice addition) apple included it in the imac because it is smaller than the first superdrive which was a bit larger than a standard size 5.25? drive. Superdrive 2 is of standard size.

    I haven't tested it, cause I don't feel like spenidng the monye too, but I've heard that under OS X, the superdrive can use DVD-RWs (Hewlett Packard kind DVD-RWs)



    I guess it's pretty simple - it just re-writes (doesn't ask or anything)...I'm not sure, but that's what I've heard.

    PS-it's a software thing, so it doesn't work like that under OS9

    Hewlett-Packard is part of a the consortium that developed DVD+RW. DVD+RWs can be read in DVD-RW drives, but they can't be written to. The same vice-versa. A DVD+RW drive can read DVD-RWs, but not write to them.



    DVD+RW technology allows you to write to discs like you would a HDD. DVD-RW forces you to write a session, then maybe another session...then erase.

    Are you sure? I was under the impression that DVD-RAM could be treated like an HDD (i.e. true random access), whereas *all* the other standards work like CD-RWs (i.e. sessions or packet writing) with increased capacity. I'll try to find a link somewhere, but maybe you happen to have one at hand proving me wrong?
