--> When the DVD player quits working properly, first the "System Info" shows the endless rainbow disk ...
Then I force the reset of my MBP, and after this new re-start, the message given by the "System Info" command, by clicking in "Gravure de Disque", is :
"Aucun périphérique de gravure n’a été trouvé. Si vous utilisez un périphérique externe, veuillez vous assurer qu’il est correctement connecté et alimenté."
Even if this message is in french, it appears that the DVD player is no longer seen by the OS system ??!!
-> In the other cases, here is what can be seen through the same commands !! :
"TSSTcorp CD/DVDW TS-L632D :
Révision du programme interne : AC01
Interconnexion : ATAPI
Gestion de la gravure : Oui (prise en charge de lecteur générique)
Chemin du profil : Aucun

One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...
--> Unfortunately, the problem remains the same. Does it mean that my pb is not an hardware matter ?
Do you want me to post here the report obtained after authorization correction in Safe Mode.
--> What do you mean by "for 3rd party Pref Panes ..." in the "System Preferences"?
For me, the 3rd line contains : Mobile Me + Share + Quick Time + Network ...
--> I did not find the files you mentioned above ; however I do not know how to view invisible files with OS ... :-(
Thanks again and happy new year 2013 !
If you had 3rd party prfs pane, they'd be in a new bottom row called Other.
Invisibility Toggler - 1.1...
InVisibles - 1.5...
--> In the System Prefs, in the row called "Other", I have the following inputs : Distribution Tex, Fan Control, Flash Player, Growl, MacFuse, Norton QuickMenu, NTFS-3G, Perian and Version Cue CS3.
--> Always in the System Prefs, in Accounts, and through my Login, the applications appearing when opening a session are : AdobeResourceSynchronizer, Wireless Utility, Spanning Sync, iTunesHelper.
I hope this may help you to advice me ... because it's a real crazy matter !
1/ Following your advice, I suppressed Norton properly, using a Symantec un-install tool ... but unfortunately the matter remains the same :-(
2/ About one of your latest advice :
"Also look in these if they exist, some are invisible...
Yesterday I searched in the wrong directory !!
Indeed, in "Machinstosh HD" directory I just found now :
--> / private / var / run / StartupItems
does not exist
--> / Library / StartupItems
4 folders : ChmodBPF, FanControlDaemon, gpibenumsvc and nipal
--> / System / Library / StartupItems
2 folders : WiUtilityUSBStartUp and DWAUSB
--> / System / Library / LaunchDaemons
132 files .plist and .wps
--> / Library / LaunchDaemons
4 files .plist
What should I delete ?
Thanks again and regards.
It is true that I did not put a DVD player identical to the original, since the Toshiba-Samsung replacement does not present itself as a "snap disc", hence the need to rectify the metal casing of my Mac BookPro.
But it seemed to me that all DVD player-burner could agree ...
If you think I should test another one, no pb : now, thanks to the in line tutorial and some specific tools, I only need approximately 10 minutes to open my MBP ...
The matter still remains the same !
If I sum up the prob for people recently connected to this site :
whatever the mode I use (regular boot or safe boot), and whatever the user (current admin user or new admin user), the DVD player-burner of my Leopard MBP works properly before the first standby of the computer (either by clicking on the standby function in the apple menu or by closing the computer) ;
but after this 1st standby, the Disk Utility runs endless, and the DVD drive no longer mounts disks
And if I try a second standby, this standby is not instantaneous but requires almost 30 seconds!
Should I deduce that internal non "snap disc" DVD players are not compatible with Mac OS systems ?
Thanks for any advice !
