I bought 200 dvd-r's manufactured in Taiwan and made by CMC magnetics. I have yet to burn any coasters or have any problems with them playing back.

Some burners do actually do a decent job with CMC.


That said, many of us will swear that they've done plenty to earn their reputation. We'll check back with you in 6 months.

 

[rudytx]

wait a few months and try to read your discs again

 

[Mr2Spyder]

I know they have a bad reputation however I had already bought 200 hundred of them before I realized my mistake. I didnt realize that name branded DVD-r's such as Panasonic were manufactured by CMC. I also have 200 maxell and Taiyo Yuden. I want to use up the cheap media first and going forward I plan on buying and using only Maxell and Taiyo Yuden.


That being said CMC claims to be the leading manufacturer of blank dvd-r media with a 30% market share. With those kind of numbers aren't you going to naturally have more complaints/problems with them. There has to be some people who have had success with this media. If they were really that bad and unreliable I cannot imagine them staying in business for very long. I'd be interested if anyone has had success over the long run with CMC media. Anyone??

I've burned hundreds of CMC-manufactured discs (under the Memorex and Imation brand names) and have not had more than 2 or 3 bad discs-which matches the failure rate of my experience with Fuji, Maxell, Verbatim, Sony etc.


CMC gets a bad rap, which may be partly due to their association with Memorex. CMC, Ritek, Prodisc etc. all produce various grades of media based on client specifications and price points. The grade of disc that CMC produces for Memorex or Office Max is not the same as the grade of disc they manufacture for Panasonic. Therefore, it isn't accurate to dismiss any product carrying a CMC ID code.


It wouldn't be too far-fetched to discover that your next spindle of Maxell discs is made by you-know-who.

RUDYTX - Please explain your statement. What info and from what sources. I'm beginning to see other posts on 'burn fading'. I think this issue is more important then media compatibility and needs to be taken seriously. But first we have to have facts. Or, as Spencer Trillby said in True Lies do you have 'any hard data'.

At the moment, it's a rehash of the Chicken Little story. The only emerging verification of disc failure is coming from the poor souls who invested in media from the now-defunct Vivistar.


To my knowledge, no one has been able to verify the root cause of the Vivistar failures or even if the problem was isolated only to specific batches. In any case, the newly-coined term of "burn fading" being thrown around is not only inaccurate, but is being tossed out in very irresponsible ways by people whose issues may be the result of any one of a number of variables.

I found the following information from videohelp.com. My Khypermedia are:


CMC MAG. AF1 4x


Plays on 12 DVD Players

Plays not on 0 DVD Players

Burn Reliability is Good

DVD Reliability is Good

PC Reliability is Good

Console Reliability is Good



According to the user comments at videohelp the cmc media appears to be rather reliable. Maybe CMC has improved. Some of their other DVD-r's received poor or mixed results.

Recently noticed 25X spindles of Khypermedia CMC MAG.AF1 on sale at Office Max for $10 ea. Looked at the videohelp.com info Mr2Spyder pointed out and decided to buy 3 spindles.


Have used one spindle with one coaster. Hopeing for zero coasters on next 2 spindles.

I've also been through a spindle of these. No problems at all burning them or playing them back. I don't think I'd trust them for anything really important.

 

[Mr2Spyder]

Its been three months and still no problems with CMC. I ran a Kprobe scan of several cmc, maxell, and taiyo yuden and the cmc consistently had lower numbers of the three. Go figure.

 

[RonDawg]

CMC-coded TDK's that were burned many months ago still play fine. I too have had no problems with them, in fact I've had more issues with RicohJPN coded TDK's than the CMC's.

I come from the computer DVD burning crowd, I've got a Pioneer 420 on the way and it'll be my first experience with a DVD recorder. I'm looking for some of the more affordable, reliable discs to use with the recorder. I've had great success with CMC discs on my burners, but I'm curious to know if anyone's used CMC discs with Pioneer recorders and how the results were.


Alot of discs will burn great on one brand of drive and burn like crap on another, even typically very good media can exhibit this. Mr2Spyder, your profile says you are using a Panasonic recorder, do you know if the dvd drive they use is a Panasonic drive, or if they put in another maker's drive? As an example, in the computer world NEC drives do very well with CMC media.

Since the Pioneer X20 series of recorders use Pioneer burners (A107), they are very media tolerant and produce discs exhibiting excellent compatiblity with virtually all brands of media I've tested...much unlike another popular manufacturer.

 

[johnacash]

So the x20 series still use the 107 as their burner? I thought maybe I'd read that the series of Pioneers before these used them and that these do not use them (something about these not using the 107s and not being able to replace the drives in them as you could in the earlier models as they no longer used a regular computer style drive). I probably misunderstood what I read, as the 107 is an 8x burner and matches to the speed of these recorders.


Thanks for the info Jeff, good to hear they have been media-friendly, I've got some CMC I'd like to use


edit: I just read on another forum that it is in fact a 107, this is certainly a plus I'd say. Now I'm getting the crazy thought of updating the firmware of the drive. No, wait, it is a -R only drive in the x20 series, hmm, I'd never be brave enough to mess with the firmware, it may well be using a special firmware just for these recorders.

 

[Mr2Spyder]

Well ive had a few CMC that seem to have gone bad. Im sticking with taiyo yuden. They can be purchased online for just as cheap as the cmc.
