Certain Music CDs Not Recognized by SONY DVD RW DW-Q28A Superdrive

Subject drive recognizes all DVDs, CD-ROMs, and some (but not all) commercial Compact Discs. Case in point is "Diva," published by Nemo Studios under license to Angel Records. This is an audio collection of Sarah Brightman's performances. Inserting this disc (and probably others) into my PM Dual CPU 2.7 GHz G5 results in "spin-stop-spin-stop-eject." No icon appears; the disc will not mount. I have verified that other CDs mount and their contents will play in iTunes with no problem. The disc in question also mounts, opens, and plays perfectly on my wife's Windows PC.
The firmware of my Sony drive is "KAS7." Is there an available update? Could that be the problem?

"as I wrote above, after it failed to mount, my wife put it in her Fry's PC CD drive and it played perfectly. "
Mac drives are more sensitive than the pc drives. My pc drive plays anything including cracked CD/DVDs.
Again, try a drive cleaner. Another thing you can try is to repair permissions & restart your computer. Sometimes that is all it takes.

On my mac, when I try to import certain music CDs (not all) I get this message "You dont have write access for your iTunes media folder or a folder within it. To change permissions, select your iTunes media folder in the finder, and chose file get info"

I am not sure how to fix this and it is driving me crazy can anyone help?
Thanks.

Hi folks,
I've had this issue for a year now and I've read this and several similar articles on how to change permissions for you iTunes Media folder and all that enclosed stuff.
Well today, I got brave and dove into this issue once again and to my surprise I have it remedied.
Before I kept going to my side bar folder 'Music', then located the iTunes Media folder ( I have several libraries).
This time, I went from (your mac)HD, directly to the 'Library', scrolled to 'iTunes' and reworked my permissions there by creating a new user... (ME). While at it, I adjusted 'Administrator from and back to, 'read and write', gave myself, 'read and write' and left other users as 'read only.'
I then applied to all enclosed folders with the 'gear wheel,' locked the whole shabang up and proceeded to install several old CD's which refused to import in the past.
RECAP:
HD/Library/iTunes set permissions for YOU to 'read and write,' then apply to all enclosed folders.
BTW: those enclosed folders are likely to be all the albums you've collected previously.
Perhaps, the 'iTunes Media folder' description from previous instructions kept people looking in the wrong place.
In any case, I'm up and running and I hope you will be too.
Thanks,
PS

I have an external firewire burner; it never shows on the desktop unless I insert a CD or DVD - that icon will then show (if I have my preferences set to show those on the desktop). Hae you checked in Disk Utility (Applications > Utilities) to see if it is listed under drives?

Can my SONY DVD RW DW-Q28A write HD DVD content?

I am trying to figure out if the Sony DVD drive/burner in my 2.7 Ghz DP G5 will write HD content with DVD Studio Pro. If so, what media is allowable. Drive model is: SONY DVD RW DW-Q28A. Any help would be appreciated.

Assuming you have DVDSP version 4.0.3 or higher, you can create HD DVDs on regular DVD-R or DVD+R discs. However, there are a few things to keep in mind:
1) In DVDSP, you'll need to set your HD DVD disc up as red laser.
2) The red laser discs you create will not meet the official HD DVD spec for red laser discs, and as such, may not play in some HD DVD players. You should be able to play them fine using Apple's DVD Player using version 4.6.5 or later.
3) These discs will not play at all in a standard definition DVD player.
The DVDSP 4.1 manual, on page 20, states:
"In addition to blue laser based DVD media, an HD project’s DVD video zone can be written to DVD media based on the red lasers used by traditional DVDs. (The obvious limitation is that you will not be able to fit as much video data on the disc.)
Important: SD-based DVD players are not able to play DVD projects containing HD content, whether they are on red or blue laser media. Additionally, only HD projects on special 3x DVD-ROM red laser media are officially supported in the HD DVD specification. You can burn HD projects to traditional red laser media on your system; however, the discs might not play in all HD DVD players."

No 1x burning with Sony DVD RW DW-Q28A

My 2.7 GHz/Dual Power Mac G5 comes with the Sony DVD RW DW-Q28A. I am unable to burn a DVD at 1x. Why would I want to burn at 1x you ask? At lot of DVD Players will only recognize 1x and 2x burned disks. We have the ridiculous situation of having to create DVD's with the Dual G5 and then transferring our creation to an 800 MHz iMac in order to burn at 1x so that people don't return the DVD's. My daughter recently had her PowerBook fixed by Apple. I noticed that part of the fix was installing a Matshita DVD-R UJ-825. That drive is also able to burn at 1x speed. Is it that this Sony model is "speed challanged" or is it just a problem with my drive?
I don't even know if buying 1x and 2x media is a solution with this particular drive. I have also read that there might be a firmware upgrade available for it. Unfortunately, from the directions I read, I would need to remove the drive and use an external USB connection with Virtual PC or install it on a PC and flash there. Are there no other solutions?

There is no official Apple firmware update for your
drive - using non-Apple firmware will void your
drive's warranty.
Regarding your trying to burn 1x: Try another brand
of DVDs and make sure that their speed rating
includes 1x
The same brand I used to burn on the laptop at 1x was used on the G5. It just seems that the Sony drive is "too stupid" (okay tha'ts not a technical term - lol) to listen to Toast when I request a 1x burn. On the Powebook with the non-Sony drive when I tell the software to burn the disk at 1x, it does, taking over 40 minutes. The blank DVD's I'm using are Verbatim 16x that are rated "up to 16x".
Just to make it even more clear, I have no problems burning 16x discs using the Sony drive. They are readable when used on my computer and on very modern DVD players that have DVD drive transports originally designed for PCs. They just won't play, for instance, on my Sony DVP-S500D which is a much older machine. When I burn at 1x on the iMac or Powerbook it plays fine on the S500D.
At the end of the day, if the drive won't burn at 1x what's the difference if Apple voids the warranty on a drive that can't be used for the purpose for which it was intended -- namely the creation of DVD's that will play to a wide range of DVD players.

Hi, after update 10.5.4 my CDs and DVDs will be read and play in the Optical Drive, But when I insert a blank one, any kind, the finder will open and when I select to mount it "media not recognized" comes up. I have the same DVDs that Ive been burning to till this update with no problem at all.
I already did permissions repair.
Please help.
Many Thanks!

I have a problem pretty much like that too, I updated my mac, and now my superdrive won't read my discs, but unlike yours, it spits the disc out.
I did find out that it can recognize DVD +R, sometimes, but it can nolonger recognize DVD -R.
Also my superdrive makes a sound like this: http://www.imeem.com/people/2tOboJ/music/gQwemcsY/superdrive_problemwav/
Sorry if I'm hitching on your post Alex, I also have another problem, and that is I can see the "reply to this post" icon but I cant see any icons that say "post new topic" anywhere, I wonder why. =(

Drive not recognizing Blank Princo DVDs

I just ordered and received 200 Princo 4x DVD-Rs because I have one of the early G5s with the Sony DVD RW DW-U10A, that is a 4x writer. These Princo blanks seemed to be some of the only 4x DVDs still around. Now when I put them in drive, my G5 doesn't recognize them, they spin around for a couple minutes, then the drive just kicks them out.
What's weird is, the drive can see and write to 16x Memorex blanks just fine. And when I put the 4x Princos in my girlfriend's MacBook Pro, they are immediately recognized and work just fine. What gives? Ever seen anything like this? It bums me out that I went to the trouble to purchase 4x speed DVDs to avoid complications, and that seems to have completely backfired on me.
Any advice or thoughts would be appreciated.

Yeah, thanks for the advice. It has been a finicky drive for me, but in general has given me almost no bad burns over the past 4.5 years, this is the first time it's rejected media.
Those Princo DVDs though, they are the white tops, they feel really light, and I'm thinking that they're not much in terms of quality...oh well, I had been using Yuden's for the past few years with great results, but when I could no longer get their 4x media, I thought the most important thing (based on some misleading posts I read) was to acquire 4x media.
Anyway,
Thanks everyone for the responses.

DVD's not working on Sony dvd player

I just bought some TDK DVD-R 16x. I burned a DVD with my iMac G4 in iDVD. I tried to play it in my Sony DVD player and it said it was was not allowed because there were limitations or something. Can I fix this or do I need new DVDs??

Suggest you create a disc image and then burn the
DVD. File/Save as Disc Image...
http://docs.info.apple.com/article.html?artnum=164927
This will isolate any encoding/burning issues you may
encounter. Once the disc image is created,
double-click the .img and burn the virtual disc that
should appear on your desktop, using Toast to burn
the DVD. Disk Utility to burn the .img file. Usually,
you can select a burning speed in Disk Utility.
There are variations to this process based on which
OS X you are using...
Open Disk Utility (in Utilities folder in
Applications folder), click on the virtual disc
(maybe the .img) in the left-hand window. Click the
Burn icon. A new window should drop down and your
SuperDrive tray will open after clicking the Burn
icon. Insert a recordable DVD. (Verbatim DVD-R
preferred by me.) Click the Close button. Wait.
Select a burn speed. If you hold your mouse cursor
over the pop-up it says: "Select a slower speed to
work around burn failures," so select 4x or slower
for best results. Then click the Burn button.
-->If the virtual disk selection won't allow you to
click the Burn icon, use the .img file instead. This
may have changed in 10.3.9 and did change in Tiger.
Also, you can use DVD Player to play the virtual disk
to check your iDVD project before burning to DVD.
Launch DVD Player. File/Open VIDEO_TS (Open DVD
Media... in Player 4.6). Find the VIDEO_TS folder and
open that. (The audio folder is for DVD-Audio
disks.)
http://docs.info.apple.com/article.html?artnum=93006
I'm reading through the forums trying to figure why I am not able to play a DVD burned in iDVD that is "R", but the "RW" ones work fine.
Your post is very helpful and I've looked at the links suggested too. I just want to make sure I'm understanding. I've copied the movie to my hard drive using iMovie and then created an iDVD project. I then need to use either Disk Utility or Toast to make the DVD. I do not need to use the "burn" feature in iDVD. Is that correct?
I would appreciate any other suggestions. Maybe there is something else in the settings or preferences I need to adjust.
Thanks so much.

5530 music player not recognizing new songs

hi all,
new problem for me. the nokia music player is not recognizing new music. it just files them under unknown. the files are properly tagged. the only way to get it to recognize the files is to format the sd card and put the music back on the card.
also after deleting music, the player still has the files in its unknown folder, even after updating the music library.
very frustrating as i use the phone everyday as my main music player. this problem has only turned up in the past couple of weeks, with me changing nothing else on the phone.
any advise?
Solved!
Go to Solution.

Hi, just try up this found somewhere-
You can do this to rebuild the library as it is corrupted.
Restart your device and then refresh your library. If this doesn't help then;
Connect the phone to your pc/lappy and put in 'Data transfer' mode.
To delete the library files:
- Ensure you can see hidden files in Windows Explorer:
Windows Explorer .. Tools .. Folder Options .. View
Select "Show hidden files and folders"
- Connect the phone to your PC using the USB cable in "Data transfer" mode
- Find and rename (or delete if you're really brave) files with names like:
E:\private\101FFC31\mpxv1.mpd
E:\private\101FFC31\pcv5.mpd
E:\private\101ffca9\harvesterdb.dat
(assuming the phone's mass memory / card has been connected as E)
Note that the folder names may be different and the files may have prefixes - eg: mpxv1.mpd could be called abcmpxv1.mpd. Basically, you need to search under the Private folder for any files that look similar.
Now just refresh the Music Player library and the job is done.
This will take longer than normal as it's a complete refresh, but it should now work.
Please thank me by giving 'KUDOS' star. It will help me to serve you better.
Currently using N82 and 5230. Next would be N?

My Toshiba Satellite p775-s7320 not recognizing the CD/DVD player (ODD)

Hello all,
I am having the problem as listed in the title in that my toshiba satellite p775-s7320 is not recognizing the built-in CD/DVD player anymore. I have the latest Bios upgrade from Toshiba. The last time this worked was earlier this year during the summer. Nothing abnormal or apparent has happened to the laptop to change anything internally, except the Bios upgrades.
Interestingly enough, there is power to the CD/DVD mechanism and the open/close features work perfectly, but the Bios can't "see" the ODD. So because the Bios doesn't see it as being attached, and the System doesn't "see" because the Bios doesn't, it doesn't matter that the Open/Close function works, because putting a good CD in with data on it is of no value.
I was considering trying to revert the Bios to an earlier one, but simply trying to load the older Bios through the Windows Bios software is a No-Go because the software won't allow me to go to an earlier Bios flash.
I'm at the end of the line with common options, other than trying to switch out the Cd/DVD for a brand new one. Something I don't want to do if I can avoid it, but I would as a last resort. As well, loading a fresh image is out of the question as I have too much accumulated software on my harddrive and don't really think the problems stims from that.
Otherwise, any other solutions may be worthwhile to try. I would really like to flash the Bios to an earlier time when the machine worked well, but I dont know how.
Thanks for taking a look. BTW, I have removed and replaced the current CD/DVD several times with no change in recognition by the Bios.

Burned CDs not recognized on PC

I burned two CDs several weeks ago with one movie each that was recognized and played by my daughter's PC. However, I have burned three other CDs with movies since then in three ways different to the first ones which were not recognized by my daughter's PC and, of course, were not played. I then burned another CD as I had the first two but this CD was not recognized by her PC.
Do you have any suggestions about burning a CD on an iMac that can be recognized by a PC? I don't understand why the first two CDs were recognized and playable and the last one was not.
Thanks for your help.
Vernon

What was the video format of the movie that was successfully recognized and played on your daughters PC? What program is your daughter using to view the CD?
The movie files were in Quicktime which she has and used to view them.
What program did you use to burn the CD?
I used a burn folder from Finder for the movie CDs.
What is the video format of the other movies that you unsuccessfully burned?
Quicktime.
All CDs played on my iMac with Quicktime and also with RealPlayer.
Any suggestions?
