Step 1: Insert DVD
Insert the original 6.8 MB DVD into your DVD drive.
Step 2: Install DVD Shrink
Download and install DVD Shrink software on your computer. It's a free and widely used tool for resizing and compressing DVDs.
Step 3: Open DVD Shrink
Launch DVD Shrink and click the "Open Disk" button to select the 6.8 MB DVD.
Step 4: Check File Size
In the DVD Shrink main interface, you'll see the size of the original DVD content. Make sure it's indeed around 6.8 MB.
Step 5: Select Compression
Click the "Backup" button in the toolbar and select the "Fit to Disc" option under the "Compression" tab. This will automatically adjust the compression settings to fit the data onto a single-layer 4.7 GB DVD without losing audio tracks.
Step 6: Re-authorize DVD
If the original DVD has copy protection, you might need to re-authorize DVD Shrink to decrypt and backup the copy-protected content. Refer to DVD Shrink's documentation for specific instructions.
Step 7: Choose Destination
Select the destination folder on your computer where you want to save the compressed DVD content.
Step 8: Start Shrinking
Click the "Backup" button to start the shrinking and backing up process. Depending on the size of the DVD, the process could take some time.
Step 9: Burn to DVD
Once the shrinking process is complete, use DVD burning software (e.g., Windows DVD Burner or ImgBurn) to burn the compressed DVD content onto a blank 4.7 GB DVD.
Step 10: Verify Backup
Insert the burned DVD into a DVD player to verify that it plays properly and that all audio options are available.
Remember that compression can slightly affect video quality, but DVD Shrink optimizes the compression to minimize any noticeable differences.
