Burned DVDs won't mount/read but seen as containing data

Hi,
I've got a problem. I have about 200 burned DVDs which were created using my LG VHS/DVD recorder/player. I have used these same DVDs to burn from my external LaCie DVD buner with my PPC G5 running Tiger and my LG Blu-Ray burning with my MacBook running Leopard and those burns plays fine on all 3 devices. However, neither the LaCie DVD burner nor the LG Blu-Ray burner seem able to read/mount the DVDs created with the LG VHS/DVD recorder/player although the G5 and the MacBook, both using Disk Utility, can see that there is data and the size of it on each disk. I am also unable to create a disk image for some reason as it begins but halts saying there's an I/O error. I need to get the content of these disks onto Hard Drives to rip and encode. How do I get the computers to mount these disks which they clearly see are not blank?
Thank you

Try opening them with mpegStreamclip:
http://www.squared5.com/svideo/mpeg-streamclip-mac.html
which is free, but you may also need the Apple mpeg2 plugin :

which is a mere $20.
You should be able to convert them to mpeg2 which is the standard format of a video DVD.

Burned DVDs Won't Mount

Recently after burning DVDs - via DiskUtility and iDVD - burned DVDs will not mount: Instead after inserting and waiting the DVD simply is spit back out. Yes, I've run Disk Warrior; did fsck -y; Onyx.
What can I do now?

woodrackets
It miight be the DVD disks. If they are newer high spead the iMac'ssmart drive may not like them. Have you updated the drives firmware?
If it's a 15" iMac see:

Give us more info. on youe system and media used for more detailed help.

Can't install Snow Leopard on MacBook Pro - DVD won't mount

I am unable to install Snow Leopard on my MacBook Pro as the DVD won't mount. This is an early 2008 vintage MacBook Pro, intel core duo...
I'm using a OS X Snow Leopard install DVD (family licensed). This DVD has been used to install 3 other Macs in my house without a problem (about a year ago), but cannot be used to upgrade my MBP. Actually, this disk mounted on the MBP exactly once - inserted with system up, the disk mounted. Upon running the installed (a year ago), the computer restarted but hung in boot. After getting the disk ejected and the computer restarted, the disk would never mount again. I've defered upgrade for a year but at this point need to upgrade my MBP at least to Snow Leopard and possibly Lion.
The problem doesn't seem to be with the DVD, since it continues to mount fine in other computers, and in fact a borrowed Snow Leopard DVD also will not mount on the MBP.
BUT ... the problem also does not seem to be with the optical drive in my computer, as it can read & mount the install/restore disks that came with the computer as well as other CDs and DVD ROMs. Only the Snow Leopard install DVDs fail to mount.
I've also tried mounting the 10.6 install DVD on my Mac Pro desktop, making it available over the network (ethernet) with DVD/CD sharing. I can mount the remote disk from my MBP that way, but when I launch the installer, the application launches (its own menus are displayed, I can quit from menu, for example) but does nothing -- no windows open, nothing.
I've also tried "Remote Install" (again with the DVD made available with the Remote Install MacOS X application on my desktop), but when I boot the MBP with option held down, the remote disk is not available as a startup disk.
Zapping the PRAM did not help.
Am off to the store to get an optical drive cleaning kit and a blank DVD big enough to burn a new disk image, but would appreciate any further ideas at this point....

Solution that worked: Copy the Install DVD to a USB flash drive and boot from that.

Up and running with Snow Leopard now and working on the updates.

DVDs won't mount - discs ejecting

(Inadvertently posted to aluminum forum -- this belongs here.)
Searched and did not find exactly this problem in prior posts.
CDs still mount and play fine, but now all DVDs won't mount and are automatically ejected. I've looked previously at region settings, decided not to change, now can't even find region settings to verify I'm still set to 1. I don't really think it's a region problem though, as I'm pretty sure I didn't even try to change regions.
Any suggestions? Thanks.

Not quite sure what's wrong here, but let's see what System Profiler (Applications>Utilities) has to say about your drive.
Open up System Profiler, then click "Disc burning" in the left-hand column. Next to "Reads DVD" what does it say?

DVDs won't mount after Security Update 2006-004

DVDs won't mount after installing Security Update 2006-004 via the Software Updater in OS 10.3.9. CDs work OK.
I've repaired permissions, reset PRAM, tried booting in OS 9.2.2 but can't get the DVDs to mount/play or be seen by disk utility.
Please help.
iMac 400mhz
Original Matshita DVD-ROM SR-8184
iMac Firmware 4.1.9
Thanks

How recently before installing the Security Update did you use the DVD drive (for DVDs)? If it was not immediately before the update, the two are probably not related. Also, if you restarted in Mac OS 9 and the DVD drive still does not work, it would seem to indicate the problem is hardware, not software.
You can try opening up the iMac and checking the connections to the DVD drive. Also, it is possible that your PRAM battery is dying (unless you have replaced it recently); that can cause unexpected problems.

Burned DVD works on PPC Macs, but not Intel

We have two identical copies of a burned DVD. When we insert it into one of the two intel Macs we have (MacPros), it spits them back out or gives read/write errors. When we put the DVD into either of the two PPC macs we have, they mount without issue.
Booting to an external gives the same error, so it's not a software issue it seems.
Has anyone else seen this before? Thank you for any help!

Are these just data discs? Or are you trying to use them for booting the computers? If it is the latter, Intel boot discs cannot boot PPC and vice versa. If it is the former, it's definitely a bizarre sounding problem. Unless, of course, when you say "when we instert it into one of the two intel Macs.." you literally mean only one of the Mac Pro's gives you problems then it's probably just a faulty drive. But if both give you problems, well, then it's still a bizarre problem.
Try feeding us with more details. OS versions, disc types/formats/contents, DVD-R drive models, whatever you can think of to help us help you.

Blank DVDs won't mount

My iMac mounts DVDs containing content, but ejects blank DVDs without mounting them. Same problem with CDs.I reset the PRAM, but this did not cure the problem. Anyone have any other suggestions? Does my iMac need repair?

You need to check what DVDs your player/recorder can handle.
Go to the System (apple) menu and choose ‘About this Mac’ then click on the ‘More Info...’ button.
In the contents column of System Profiler choose ‘Disc Burning.’
Now look at CD-Write and DVD-Write and Write Strategies in the right hand pane. These are the types of media you can use. Many iMac G4 units could read, but not write DVDs.
If your iMac can write to CD/DVD, you are using the proper media format, and your drive STILL will not burn, then the burn lasers may be malfunctioning or dirty. Try using a CD/DVD cleaner (actually, a spinning brush) to clear off dust and dirt. If that won’t work, then you probably need to replace the drive.

Burns DVDs, WON'T play commercial DVDs

So I seem to be having the REVERSE problem from everyone else. My iMac G4 (17", 1GHz processor, 512 MB RAM), which I just bought for a piddling $200, will play and burn CDs / CD-RWs just fine. It will also correctly identify blank DVDs that I stick in the drive. It will BURN DVDs. In a few hours, I'll be able to tell you if it will read data DVDs.
The ONLY THING it won't do is play COMMERCIAL DVDs. I pop in a video DVD, it spins up, tries to read it, then spits it back out. Now, I know the not playing DVDs problem is not a unique one, but in reading on these forums, that seems to always be a symptom of the DVD laser diode having gone bad, which is certainly NOT the case here (as it's merrily burning away).
My GUESS would be that--somehow--my installation is missing the CSS library necessary to decode commercial DVDs. I had a similar problem getting my iPod Touch to talk to iTunes. But is that even possible? And, if so, how do I go about rectifying this issue?
Any help would be greatly appreciated.

I FIXED IT!!!!!!
I read somewhere else on this forum about someone having a similar problem to mine. He took the iMac to a service depot, but when he got it there, they couldn't replicate the problem. He took it home, and HE couldn't replicate the problem. As in, it was now fixed. Turns out that just unplugging the unit gave the Superdrive a chance to "reset."
So I unplug my iMac to test this out, as well as to see if I can unscrew the access panel to determine how easy it'd be to upgrade its RAM. Well, I could only get one of the screws out, but when I plugged it back in, turned it back on and popped in the collector's edition of "2001: A Space Odyssey," DVD Player came up and began playing the disc! Never has "Thus Sprach Zarathustra" sounded so amazing!
So, thank you, John Westwood1! Thank you!

DVD won't mount in 10.6.2 - possible bug?

I'm sorry if this seems like a cross-post but I believe I've narrowed my problem to SL 10.6.2 and don't know where else to post this.
DVD will play in standalone DVD player but NOT mount on the computer that created it. I have confirmed that it will mount and play on a bootable backup I had made (10.5.8) before upgrading to Snow Leopard. Another reader posted the same problem on the thread.
please take a look and tell me what you think...
http://discussions.apple.com/thread.jspa?threadID=2260033&tstart=0
thanks so much,
Pale

The DVD will also mount in 10.6.1 (I had a bootable clone of that installation, as well)
to recap...
I created an iDVD project. Saved as an .img file. Burned to DVD.
Those DVD's will not mount on the computer and OS it was created on.
They will mount on the same computer booted into clones of 10.5.8 and 10.6.1
They will play in standalone DVD players
They will mount on a friends Tiger installation 10.4.9

DVD won't mount (again !)

This topic has been on a few times, but none of the aswers worked for me.
I have a powerbook 1,66GHz Al that won't mount a DVD-R (noise for about 15s and eject without any messages). The same DVD mount and play correctly on an ibook 1.2 GHz under 10.4.4.
My preferences are : ask me what to do for new CD/DVD. For when inserting a DVD, I tried DVD player and VLC with the same result.
I installed Tiger from scratch and did not reinstall yet any iphoto, idvd, ilife...
I'm just wondering if this is the reason that I cannot read these DVD.
Any idea ?
Bernard

I did not realise that CDs had to be finalized before use in other machines.

DVD won't mount on desktop

My superdrive in my 20" iMac mounts blank or pre-recorded Cds and will mount blank DVDs, but when i put a normal DVD in (one i bought from the shop), i will not mount on the desktop.
I am confused. I first bought an iMac towards the begining of september, but took it back and got a replacement because the superdrive was faulty (would not burn DVDs and made loud noise when burning CDs) and now, two weeks later, my replacement computer is messing up. not too impressed with these iMacs so far - or the superdrive at least.

I have the same issue, suddenly. Burned fine till recently, then when I needed to burn some yesterday it failed to do so. It's Verbatim DVDs and I have a box of 100 where of the first 20 was fine some weeks ago.
I'll try your advice and if you don't hear from me again, that was it.
Thanks anyway.

DVD won't mount on OS X Mavericks

I have some movies that I want to watch on my computer, I have a Macbook Pro (2009) with OS X Mavericks installed. I've been successful in mounting and watching some older DVD's, but these new DVD's I have won't mount, is there some sort of work around or something that new DVD's have that won't let them mount? Or is this with OS X Mavericks and some protection device?
Thanks

Anyone have any ideas or thoughts on this? Thanks!

Burning DVD, won't play

I have used itunes to burn a DVD of my music. I can't play these files in my car, which plays MP3 files, but apparently not the M4P files that itunes copies to a burned DVD. When I copy the same files to a CD audio disc they work just fine.
Funny thing is I received a DVD burned from the previous owner and it works just fine. No idea if he took his files from itunes. Anyone have a solution?
Thanks!

m4p files are protected files files from iTunes music store. These cannot be played by any car stereo I know of. You need iTunes or iPod to play m4p files.
The DVD that works probably contains only mp3 files.

Newly burned DVD won't play last chapter

I'm new to iDVD, so this may be a dumb question. I just burned my first DVD and when I put it into my DVD player it plays all but the last chapter of my menu. Any ideas?

First test is to load it into your Mac and see if it plays with Macs "DVD Player" utility.
Let us know whether it plays the disc with or without the same problems.
