Definitely.
He is right that a Blu-ray drive needs two laser pickups to read DVD and Blu-Ray, but using false evidence to back it up.
I have yet to see a Blu-ray drive that doesn't include both pickups, though.
Got a tip for us?

I'd imagine they either are or will be able to do the exact same methods used by DVD drives to read CDs...I mean it's the same idea, just smaller wavelength light.
At any rate, my PS3 does indeed play DVDs just fine, but I don't use it for that as I'd rather keep it around for PS3 (and 2) games, and Blu Ray discs.

This only works when the wavelengths are close enough together. Blue lasers require different gases to be used than red lasers, and as a side effect, you need to include two lasers in order to read discs at the two different wavelengths.
DVD drives reading CDs was fairly different, as you used basically the same laser, but instead worked on better resolution of the optical pickup so it could read more dense discs. You will hit a roof of how much data you can pack while still being able to resolve it with a red laser (because of the wavelength), which prompted Sony and their guys to switch the laser type. My understanding is that the original CD format wasn't even close to this limit, DVDs were closer, and HD-DVD was bumping into the limit.
PS2 games are DVDs.
HD-DVD used a blue laser too though, and CDs were infrared if I'm remembering correctly.

Yeah, but I mean video discs, which I have other (cheaper) devices I can play them on.

Yeah, yeah.... you guys caught me...
HD-DVD uses the same dual-laser pickup that Blu-Ray drives use. For some reason I got my information crossed. Sorry.
As for the CD comment earlier, you caught me again. Looks like what you see in most DVD drives is a dual-laser diode that can run at 780nm and 650nm using the same lens assembly. Blu-ray drives use a triplet which can power 3 diodes at 780, 650 and 405.
The dual-pickup is really for making sure that using this triplet of lasers, it can actually focus at all 3 wavelengths. It is possible to make optics that focus 780 and 650 at the same time, and make it fairly cheap. Optics that can focus all three don't come easy or cheap. It is cheaper/easier to have two optical paths to handle the 405nm laser.
That's what I get for not double-checking before posting.
I already explained that someone told me that several pages ago. I don't own one so I've had no personal experience. If you want to run it into the ground, go ahead, but it's pointless.
Finally, I hope this may result in a new MacBook Pro in July with a Blu-Ray player/writer on board... The 50Gb backup possibilities are very interesting. I always photograph on RAW format, and I'd like to keep everything I shoot so a lot of storage on a single disc would be perfect
i am with you. i definitely would love the ability to backup to BD disc.
but i also would love to watch BD movies on my laptop. i don't want to get movies all the time via itunes. i get from netflix and i buy BD discs. but i had paying exta fro a digital copy. besides, i am always out of room on my MBP hard drive. so i don't want to take up valuable space with digital copy movies.
Just another movie-nerdy perspective:
Bluray is absolutely fab for hometheater. No going back once you started watching with a decent projector...
The difference between good Bluray discs and the itunes HD quality is not subtle...and getting 7.1 audioplayback on a Mac is not trivial either.
Bluray may be a bag of hurt in many ways but it is wonderful in a home theatre. Sure glad I am alive to see it finally like this in my home, having been around since video arrived...and now owns Bladerunner on 5 formats ;-) There will not be a sixth for me by the look of it...-)
peace, FWIW, YMMV etc etc

Did it come out on HD-DVD before Blu Ray? otherwise, my guess is he ran off with a bunch of cans of film from a theater. Although, if I had that setup, not sure I would have bought anything short of the HD releases
There are also five versions of the film...

God bless you guys for your faith... I've left it
I would hope that you guys get your Blu-ray, but as for me and millions of video and audio-video pros who needed it three YEARS ago, the idea of ever again paying a premium for ultra-high priced Apple workstations nowhere NEAR the cutting edge is unthinkable.
I don't trust Apple COMPUTERS under Jobs either to ever be cutting edge again. Just a lowest common denominator toymaker producing fad after fad to be discarded a year after its release. Eventually falling prey to someone in China who will do it better and cheaper.
Try to sell a used Casio musical keyboard and see what happens.
This station left the train a very long time ago. Apple is the new Mattel producing iCrap iToys for iKiddies, like it or leave it.

You would also have to be crazy to rely it on backing ip to hard drives. Optical media are the only other realistic option for the soho market.
Tough crowd...;-)
Ok so it's actually 2 versions on 4 formats to be precise...for a grand total of 6 hardcopies, as I don't have all versions on all formats.
But then again who does...
Bonus:
Recently found out that my favourite quote from the movie is a misquote of William Blake, intentional or not I wonder...:
Blake wrote:
"Fiery the Angels rose, & as they rose deep thunder roll'd
Around their shores: indignant burning with the fires of Orc
And Bostons Angel cried aloud as they flew thro' the dark night."
Roy Batty speaks:
"Fiery the angels fell; deep thunder rolled around their shores; burning with the fires of Orc."

I do think Apple will start introducing BD-RE drives on their iMacs and Mac Pros some time in 2010.
After all, just about everything else on current Macs can support Blu-ray technology, including full HDCP support. Now that rumors persist of HDMI support, that makes it even more likely it could happen.
The Blu-ray Disc Association could offer Apple a very lucrative single-point license discount on the technology, and that could finally convince Jobs to give the go-ahead to incorporate Blu-ray technology into iTunes, iMovie, Final Cut Pro, and an improved QuickTime player.

This is a great BD set of an awesome film.
