Quality of Copied CD's?????

Obviously not.

LOL! Yeah....really. You guys got a little off track there and left us spectators on the edges of our seats waiting for the final verdict.

So when talking about CD playback we should get that stupid Circuit City look and exclaim "Its Digital!" with that all assuming look which confirms our belief that it is obviously perfect? I think not. We are not the typical people who buy bose...

Etc...


One other thought, if it is all just digital and a copy is the same as an original, then why do they often pop, clip or skip??

I guess what I'm getting at is that the data on the disc may or may not be read/written to properly by the drive. If it were always read/written properly (all a strict digital medium with no analog component) then you would never have a difference between an original disc or any copy. Copies often have many noises such as skips or pops or such. I think there is much more to this than writing 1's and 0's.

Ain't the internet great?
Oh, by the way, these are white papers written by the wonderful people who CREATED the technology known as Compact Disc.

And who else noticed the illustration sample on that page is flawed. It has two '1's separated by only one '0'. One of the reasons for EFM coding, is to spread out the length of time between Land/Pit transitions. With EFM coding there is always at least two '0's between two '1's.

What was EFM coding?

Eight-to-Fourteen Modulation, which is used on audio CDs. Each 8 bits of data is looked up in a table for a corresponding 14 bits of data. This 14 bit value is what is burned on the CD. The whole idea is to stretch the data a little. So there is more spacing between Land/Pit transitions.

Actually,

In the Jedi Order, each Jedi student makes a journey to get Illium Crystals for the lightsaber they will one day build. This journey is considered a rite of passage. As a result, Jedi sabers are many different colors depending on the crystals they find.

There is no such ritual for the Sith. The Sith prefer synthetic crystals for their sabers. The synthetic crystals save the Sith the long trek to get Illium Crystals, provide more blade tuning options, and give Sith sabers their characteristic red blade.

Well knowledged in the Jedi arts, you are!

I knew about the trek/rite of passage, but I figured that because the Jedi controlled Illum, the Sith were not able to get the real crystals. After all, the Sith were hiding from the Jedi/ the Rebulic during most of the pre-Phantom Menace time period.

By the way, to Heiney, this is NOT from the new movie. I haven't seen it yet either. Most of what I posted is from the Clone War I collection of animated shorts that was released to bridge the time from "Attack of the Clones" to "Revenge of the Sith". Its available on DVD and kind of like the Animatrix. There is so much Star Wars sub culture and lore out there, that none of this is new to the typical Star Wars Geek.

If you use a program like EAC or similar you will get an EXACT digital copy of the 1's and 0's. Yes there are other 'artifacts' that can be introduced and those artifacts maybe problems with the the drive mechanism, although not likely. As I've stated before these noises and pops most likely come from not knowing how to properly rip/burn a disc. Anything can happen, but the best results (ie; most consistent) are achieved by ripping to the hard drive with EAC and burning to a disc using the Full version of a well known burning program. There is also a little know-how involved. Also, if you have marginal system resources, don't have any programs running in the background or run any other programs simultaneously. Will this work 100% of the time, no but it will work 98% of the time. The other 2% are just random chance.

This thread makes baby Jesus cry.

Oh, and if you do a direct copy - there is no difference in the burned CD vs. the original.

I use nero 6, a duron 1.8 processor and don't seem to have a problem but friends have often burned CD's for me which have problems. My work computer has burned some bad discs but it is loaded with cad, simulation and compiler software. It is a P4 2 something Ghz also with Nero 6. I guess I just don't know how to make a proper copy. Seems to me it shouldn't be that high level but I guess maybe you have to be computer literate or something...

My comments weren't necessarily directed toward you Madmax. But hardware/software set-up/compatibility is a huge issue. Plus computers are designed to be multi-functional, not just cd copiers. So when you introduce these variables plus some people's clueless ness ( not you) sometimes you can get some bad burns.

The process involved with extracting data (again can't rec Exact Audio Copy enough!) and burning it to cdr should produce consistent repeatable results. A computer environment can be a volatile place as we all know. I hope I'm getting my point across that the PROCESS isn't the fault; it’s the implementation that can be at fault.

My old computer, which is a dinosaur by today's standards, had all kinds of trouble burning cdr's. Its main problem was the CPU speed and memory issues and internal buss configuration. I use the EXACT same process with my new computer and have yet to make a bad burn. Also if you buy a $5 ROM drive expect to have negative issues with it.

I've wonderd about that myself. Those are a product of Clear Channel and I was hoping they'd take off more than they have. Some very limited titles have been offered through BB, but none of the more popular artists.

I saw Jewel last year about a week before she announced that she would participate. Her concerts were never offered thru BB and command big $$$ on E-bay ($150-300). I'm not sure how they mix them or dupe them. I have heard from other people that only a limited amount are available. And for a while they would take your mailing info and send you a copy a few weeks after the show. I think they stopped doing that though and now you can only purchase after the actual show.

Wasn't aware they were still doing this.

There's a place http://newburycomics.com/rel/v2_home.php?storenr=103&deptnr=34 that sells them authorized.

I have two, one of Peter Frampton and one of KISS, and they sound just like an "official" live album you would buy in a store from the record company like KISS Alive or Frampton Comes Alive.

On the KISS one, you can even clearly hear the "hiss" of the flames coming up from the stage.
