TICKET ARCHIVE -> Video DVD unrecognized

Robert12345 - Aug 4, 2006 - 8:03 pm

I am running a PowerMac G4 Build 6R73 with Mac OS 10.2.8 Dual 1.25 Ghz processors. I have a combo drive (factory original) and an aftermarket superdrive installed. Video DVDs played on both drives after install. It's been about a year since I've played a DVD on my computer. Now when inserting a Video DVD, I get the following error message:

"You have inserted a disc containing no volumes that Mac OS X can read. To continue with the disk inserted click ignore."

How do get my computer to play DVD movies again? I've tried several different DVDs, including those that used to play on my computer before the error occurred, thus ruling out a format problem.

Thanks for your help.

I suspect Apple DVD Player and perhaps some basic system software has "gone south." You could delete the .plist files for Apple DVD Player, but I would do things the easy way:

Download the 10.2.8 Combo Updater from
http://www.apple.com/support/downloa...bo_10_2_8.html

I realize you're already running 10.2.8 but the combo updaters are truly things of wonder. I never let Software Update to upgrade system software; I use the combo updater. They replace a few zillion files from 10.0 or 10.1 (depending on the updater) onwards, and almost always fix these pesky problems. It will certainly do no harm.

HTH and please let us know what happens. Thanks.

Thanks for the reply. I used your link and installed the updater as suggested. After restart the problem still occurred. (I tested both drives with several DVDs). I don't know where that .plist file is. What are your next steps?

I appreciate the help.

Hi,
I keep getting reminder notices about this ticket saying user input needed, but I already gave my last input and haven't seen your follow up reply yet. Did you reply?

This is still an unresolved issue. The previous tech I had stopped replying. Please read previous posts to see where we left off.

I'm sorry that the person you had helping you seemed to have just left you hanging.
I believe that he wanted you to try throwing away the preferences for DVD Player which might clear up your problems.
To find that, go to your User folder - Library - Preferences and it will be a file named "com.apple.DVDPlayer.plist" Throw this in the trash and try another reboot.
My other questions, if this doesn't help, would be:
Are the disks not working in either drive?
Are you trying disks that are movies sold by the store or only ones that you have burned?

To rule out the DVD Player application, you can download a free player called VLC. http://www.videolan.org/vlc/download-macosx.html

Please let me know if any of this helps.

Hi,

Thanks for picking up this ticket. I did what you said but the problem with the Apple DVD player persists. I did download the free player and it was able to run the discs, supposedly ruling out a hardware problem. However, I had to tinker with the VLC software each time to get it to "find" the DVD. It did not recognize the disc automatically.

To answer you questions: the disks are not working in either drive. I am trying disks that are sold by a store which worked previously on my computer before the problem started.

Any more thoughts?

Okay. Well, we might be getting somewhere. It still doesn't remove the possibllity of a hardware problem. It does help that you are using a store bought disc.
We are probably going to have to just keep trying things until we find the solution, so I hope you can bear with me.
You said that VLC had a problem finding the disc. Did it come up with the same error? If you click "Ignore" does the disc mount on the desktop? Can you mount just regular burned CDs or DVDs?
Another thing to try is to take off the external drive and try the DVD in the internal drive. The external one might be causing an issue.

Robert12345 - Aug 15, 2006 - 3:47 pm

When I insert a DVD movie. I get the error message quoted in my original ticket. I have to click "ignore" or the computer will eject the CD. Once I click ignore, the disk does not mount on the desktop and is invisible.

Then I open the VLC program and it give me a remote control window. When I hit the play button, it generates an "open source" window. I click on the Disc tab and then click the DVD button under the "media resource locator." After clicking "okay." I'm brought back to the remote control window. Then after hitting play two times, the movie opens in a new window.

I am able to mount music CDs and data CDs both in burned format and factory originals. They come up fine.

Actually, both optical disk drives are internal. I don't have any external drives. The same problem is happening with both.

Hi,

Just checking in to see if you're still able help, as it's been about two days since I last heard from you. Please see last entry.

Thanks,

Robert

Sorry, Robert, I didn't get the notification that you had responded to my questions. I am still willing to help, but I'm not sure that I can at this point. My best guess is that it is a hardware issue though I am unsure why it is happening with both drives. I would have also thought that it would have problems recognizing discs that you have burned if it is having problems with the ones you bought. You didn't say, though, if you were able to recognize DVDs burned with your computer.
I am going to open this question back up. I am very sorry that I wasn't able to help but all of this should help the next tech. You may also want to consider taking it in to be repaired. I know it costs money, but it all could boil down to a hardware problem.
