Hi,
Well I understand your problem. You want to make a personal backup copy. So I suggested you step by step tutorial for burning DVD. This is an excellent way to ensure you are protected should your original install DVD become damaged or lost. This simple tutorial will show you how to make a reliable DVD copy from Tiger's Mac OS X Install DVD.

Step 1. Insert the retail Mac OS X Install DVD into your drive.
Step 2. Launch Disk Utility (Applications > Utilities).
Step 3. In Disk Utility, you will notice a white pane on the left hand side. In the pane, select the Mac OS X Install DVD by clicking on it once.
Step 4. Click New Image on the Disk Utility toolbar.
Step 5. A dialog box will appear. Give the new image a name. I used 'Mac OS X Install DVD'. Select the destination where you wish to save it. Leave Image Format at Compressed (default) and Encryption at None (default).
Step 6. Click Save to begin creating the image.
Step 7. Once your image has been created DO NOT mount it. Leave the image alone and proceed to the next section.
Burning the Image:
Step 1. Launch Disk Utility (Applications > Utilities).
Step 2. Click Burn on the Disk Utility toolbar (upper left).
Step 3. Navigate to where you saved the DVD image created in the previous section.
Step4. Click on the image file, then click the Burn button. Do not drag and drop the image file into Disk Utility during this step.
Step5. Insert a DVD when prompted and proceed to Burn it. (use good quality media)
Thanks

I am reluctant to diagnose a problem based on such a sketchy description. However, it appears that your blank DVDs don't like the drives in your other two computers. This is a problem with DVDs. You should identify manufacturers and specific lines of DVDs that work in both the source and destination drives. Never ever assume that any one brand will work in any random combination. Once they are burned, you must keep the media in the dark lest you end up with coasters.

For the reasons listed above, my personal experience is that DVDs make a terrible choice for data archival. CDs are far superior. SSDs, external terabyte HDs--look into these.
 
thank you for replay.

I use DVD for Data Storage for years. Recently I copied to HD 20 DVD
burned in 2005 and 2006 without any problem on the same iMac.
I have problems reading DVD burned yesterday on my 2009 Macbook Pro.
I find it strange as they mount as Blank Disc, no errors or any other messages
