iv seen that dvda has been getting more popular recentley , and i understand that it has better sound than cds (cd format: PCM@ 16bit sampel size/ 44.1khz sampel rate ,stereo ,DVDA: PCM@ 24 bit sampel size/ 192khz sampel rate stereo) iv allsow herd that it has a more robust copy protection system than normal vidio dvds. what id like to know is if there are any rip/burn programs out there that can defeat the copy protection and rip the tracks digitaly to my comp as wav files with the same 24/192 specs , so i can back up my discs/make mix dvdas/use my comp as a jukebox etc if i decide to start building a colection of these new hi-res music discs?

i remember it took a long time for dvd video css to be broken ,but if dvda hasent been cracked yet what might the eta be for a good rip/burn program??

if they cant be copied/ripped/backed up, i will simpley not buy any of these things.

I'm not too sure about that. It seems to me that DVD's are almost impossible to make completly copy protected. I base that thought on the fact that they must somehow be read by a player. Some program will be written to decode the new protection system. Just like CSS, this new protection method will eventually be cracked. I think that a new format like this will replace the current DVD encoding. Now disks are being developed that can hold as much as 100GB of data on a single side. This will allow for the size and quality of the video to increase. My $0.02.

CSS was hacked because Xine's DVD player software stored the
decryption key in a unsafe way so that it could be easily retrieved. Older DVD-Audio disks used CSS, newer (after 1999) do not. I don't think there's any software to play such DVD-Audio media. CSS was very weak anyway, so it wasn't even necessary to have a real key. You can simply restore a working key by brute-force within a few seconds on every half-modern PC.

The next version of MS Windows i.e., Longhorn might make it (close to) impossible to hack software as it happened with the Xine DVD player (see http://en.wikipedia.org/wiki/Fritz-chip). Also the new protection system CPPM uses a stronger algorithm and it's really mean as it's able to revoke hacked keys. This works by putting black lists on DVD-Audio disks released after they found out about the hacked key. However, *if* someone really hacks the whole system, he could easily create a disk that will blacklist *all* possible keys. Just consider what would happen if this hacker managed to modify a master disk before it's pressed.

There have been PC magazines with CD-ROMs that contained virii before.

Last but not least, if people are more than happy with "crappy" audio quality of an iPod or iRiver, why would they buy a DVD-Audio system? The electronic isn't the problem but
speakers that can actually reproduce something better than what you get from CD-Audio are quite expensive. An average audio system doesn't even come close to full CD-Audio quality
(especially at both ends of the audible spectrum). However, the success of iTunes and P2P indicates that audio-on-media is close to dead. SA-CD and DVD-Audio will certainly stay just vinyl but their main market will be audophiles and such.

in that case im definantley going to boycott DVDA. (unless cppm gets cracked).

i personaly think cds sound great...im pretty shur upping the sampel rate/size from 44.1/16 to somthing higher wouldent do anything sound qualety wize anyway. suposedley the 16/44.1 method a cd uses can perfectley reproduce any sound up to 22khz (i think about 22khz is the limet for human hearing).

i think dvda is a marketing scam attemt to make people re-buy all there music and to use somthing with heavy copy protection.

Yes, the real limit is actually lower than 22 kHz and it becomes lower while you age. I don't know how they justify the 192 kHz sampling rate. Actually, most audio CDs are mastered so badly that the quality stays far below the possible. Usually, tracks are recorded too loud so that they still sound "good" (whatever that is) on a pocket player. Thus, you lose a lot of dynamic on a CD due the 16-bit resolution. The 24-bit sample resolution might therefore improve things but they could as well master the CDs properly and this little improvement hardly makes up for all the disadvantages.

I could even imagine, that they would purposely decrease the record quality of CDs in order to convince people of the "superior" audio quality of DVD-Audio.

How do you want to record tracks from a DVD-Audio to your pocket player or car player? You'd either have to buy special hardware or record analog (now comes the bummer) in realtime! I have a Minidisc recorder/player and this was the main reason I recorded very few discs. It's just too much hassle and time.

and i thought i had too much spair time...

how much did u pay for this thing??

i payed 20$ for my sony headphones...if i were to pay 230$ for headphones theyd better be magic headphones that grant wishes.

PS i tride to put a picture in my poast...if you dont see a cheeseburger , i screwed it up...

Are you talking about in-ear headphones for a walkman? Well, the price itself is not a good indicator for quality but you cannot really compare those with "closed" headphones that cover your ears completely. It also depends on the sound source of course. For a portable player those should be fine. My analog soundcard output is OK but far too noisy, in contrast the onboard soundchip sounds like crap - no kidding. Therefore, I (ab)use my minidisc recorder in pass-through mode - my soundcard is cheap but has an optical SP-DIF output. The minidisc recorder has a much better DSP than the PC soundcard.

I think 100-200 EUR is a reasonable price for good headphones but you really have to compare and test a few models because they sell a lot of crap in the same range. For example, some may have much deeper bass than others but totally suck at high frequencies or vice-versa. One thing that is often underestimated is the wear comfort. I have one set that either causes headaches because it's too tight and puts pressure on your skull or otherwise (if adjusted) kills your earlaps by too much pressure. Well, I should have believed the reviews but the bass qualities blinded me.

Anyway, I switched back to the older set (same brand coincidentally) which I can wear literally all day without any discomfort - I hardly notice them. In any case, stay away from wireless headphones unless you're willing to pay 500-1000 bucks for a proper *digital* set.

Just like with almost every tech gadget, there's a top of the line and a bottom of the line product. I'm sure that the range of sounds reproduced in an expensive pair of headphones is much greater than that of a cheap-o pair or Sony earbuds. That's the difference between these and these.

my headphones are not the little plug things that stick in your ears....they are the over the head kind that compleatley cover your ears. and they sound verry good ,all frequenceys come thru verry clear and perfect. responce is 16hz to 22khz. just because somthings cheep dosent meen its crap, and just because somthings expensive dosent meen its top of the line. there model # is : mdr-v150 .

eating enough miky-Ds will probobley kill you (i watched supersize me) . but once or twice a week max, is fine.

actualy a bag of fertalizer costs bout 5$ , so tecnicley you can get 4 bags of sh*t for 20$

i thought when you sed u hand built it you ment you soldered it all together and etched your own pc boreds etc .wich would take a lot of spair time.

135$ for a sterio like that? that still seems pretty low even for 1970s money....but im not famillar with aus money so im probobley wrong. my sterio cost about 400$ , thats what i was using as a referance point.

my wall-mart sonys headphones are fine for what i use them for...i do intend on buying a reely nice sterio and a 200$ pair of good headphones. (the 400$ sterio i mentioned erleyer is actualy my moms)...

the pc is ...ummm...well...OK, but im still having problems...i may have to get a differant kind of memory (its still crashing after i got dsl) and i may have to have my 300gb music drive replaced , it sez in the "event viewer' thing that it has a "bad block" wich im asuming is the same as a bad sector ...no worries...its all under warrentey and i backed up the entire thing once i found out this little suprize.

along with othor stupid little things...a dll went missing and i had to replace that , for some reson my email and internet browsing dont work too good, IE gives me the "page cannot be displayed" routine and OE wont send and receve , but all my p2p downloads fly and go fine ,so i think the net problems are at the isp end .
