What copying a DVD actually means

Copying a DVD means reading the video, audio, and menu data from one disc and writing it to a blank disc so you have two identical copies. The process involves three separate steps: reading the source disc into your computer, converting or preparing that data if needed, and then burning it onto a blank DVD.

Most people think of this as a single action, but your computer is actually doing distinct work at each stage. The reading part extracts the files. The middle part checks whether the data needs reformatting (usually it does not). The burning part writes everything to the blank disc at a controlled speed so the data stays readable.

The time this takes depends on your disc drive speed and the amount of data on the original DVD. A single-layer DVD holds about 4.7 gigabytes. Most drives can read and write at speeds between 8x and 16x, meaning they can theoretically complete the job in 30 to 60 minutes, though real-world timing is usually longer because drives slow down partway through to may support accuracy.

Key Takeaways

  • You need three things: a source DVD, a blank recordable DVD (DVD-R or DVD+R), and a computer with a DVD drive that can both read and write.
  • Most DVD copying software reads the disc into a temporary folder on your hard drive, then burns that folder to a blank disc in a separate step.
  • Blank DVDs cost between 20 and 50 cents each when bought in bulk, and the entire process takes 45 minutes to two hours depending on your hardware.
  • If the original DVD has copy protection, you will need software that can decrypt it first — this is legal in most places for personal backups but not everywhere.

The hardware you need to get your free guide

Your computer must have a DVD drive that supports both reading and writing. Many laptops have drives that read DVDs but cannot write to them. You can check this by opening your device manager (Windows) or System Report (Mac) and looking for the drive model, then searching the manufacturer's specs online. If your built-in drive cannot write, you can buy an external USB DVD drive for $30 to $60.

You also need blank recordable DVDs. The two common formats are DVD-R and DVD+R — they work almost identically, and most modern drives support both. Avoid DVD-RW (rewritable) discs for this purpose because they are slower to write and less reliable for long-term storage. A spindle of 50 blank DVDs costs roughly $10 to $15 online.

Make sure you have at least 5 gigabytes of free space on your hard drive. The copying software will create a temporary folder while it reads the source disc, and that folder needs room to sit until the burn is complete.

Software options for reading and burning

Windows includes basic DVD burning through File Explorer and Windows Media Player, but these tools work only on unprotected discs. You insert a blank DVD, drag files onto it, and click "Finish burning." This works fine if you are copying a home video or a disc you created yourself.

For commercial DVDs or discs with copy protection, you need third-party software. ImgBurn is free and widely used — it reads a disc into an image file (a single large file that contains everything on the disc), then burns that image to a blank disc. DVDFab and WinX DVD Copy are paid options that handle protected discs and offer more automation, meaning fewer manual steps.

Mac users have fewer built-in options. The Finder can burn unprotected content, but for protected discs you will need third-party software like Mac DVDRipper Pro or Handbrake (which is free but converts the video to a different format rather than copying it exactly). Many Mac users find it simpler to use an online service or borrow a Windows computer for this task.

The step-by-step process for an unprotected disc

Insert the source DVD into your drive and open your copying software. If you are using ImgBurn on Windows, select "Read" from the main menu. The software will ask you where to save the image file — choose a location on your hard drive with plenty of free space. Click "Read" and wait while the software copies everything from the disc to that single image file. This usually takes 20 to 40 minutes.

Once the read is complete, insert a blank DVD into your drive. In ImgBurn, select "Write" from the main menu and point it to the image file you just created. The software will ask about write speed — the default is usually fine, though selecting a slower speed (4x or 8x instead of 16x) can improve reliability on cheaper blank discs. Click "Write" and wait for the burn to finish, which typically takes another 20 to 40 minutes.

When the burn is complete, the software will eject the disc automatically. Test it by inserting it into a DVD player or your computer to confirm the video plays and the menus work. If something went wrong, the disc may be unreadable — this is why it is worth testing before you discard the original.

What to do if the disc has copy protection

Commercial DVDs sold in stores usually include CSS (Content Scramble System), a form of copy protection that prevents your computer from reading the disc in the first place. If you insert a protected disc and your software cannot read it, this is why.

Circumventing CSS is legal for personal backup purposes in the United States, Canada, and most of Europe, but not everywhere — check your local laws before proceeding. If you decide to go forward, you need software that can decrypt the protection. DVDFab and WinX DVD Copy both handle this automatically. You insert the disc, select "Copy," and the software reads and decrypts it in one step, then burns to a blank disc.

The decryption step adds 10 to 20 minutes to the total time, and the software usually costs $30 to $80 for a perpetual license. Some people choose to rent or borrow a disc, make one backup copy, and then return it rather than buying the software.

Common problems and how to fix them

The blank disc is not recognized. This usually means your drive cannot write to that particular brand or format. Try a different brand of blank DVD, or check whether your drive supports DVD+R versus DVD-R (they are different, though most modern drives support both). Older drives sometimes only work with one format.

The burn fails partway through. This often happens because the blank disc is damaged or low quality, or because your drive is overheating. Let the drive cool for 10 minutes, try a different blank disc, and select a slower write speed in your software settings. If it keeps failing, your drive may be failing — external USB drives are cheap enough that replacing it is usually the practical choice.

The copied disc plays in your computer but not in a DVD player. This usually means the blank disc format does not match what your player expects. Try burning to DVD-R instead of DVD+R, or vice versa. Some older DVD players only recognize one format. You can also try finalizing the disc if your software offers that option — it writes a table of contents that some players need.

When copying is not the best option

If you only need to watch the video once or twice, streaming or renting is usually faster and cheaper than buying blank discs and spending two hours copying. If you want to edit the video or convert it to a different format, copying the disc exactly is the wrong approach — you would instead use video editing software or a converter.

If you are trying to copy a disc that belongs to someone else, or a commercial disc you do not own, that is copyright infringement in most places regardless of whether the disc is protected. The legality of copying applies only to media you own.

If you need the backup to last more than five to ten years, recordable DVDs are not reliable — the dye layer degrades over time, and many discs become unreadable within a decade. For long-term storage, external hard drives or cloud backup are better choices.

Frequently Asked Questions

Can I copy a DVD without a computer?

Not practically. Some standalone DVD recorders exist, but they are rare, expensive, and designed for recording from television rather than copying existing discs. A computer with a DVD drive is the standard approach.

Is it legal to copy a DVD I own?

In the United States and Canada, making a backup copy of media you own is legal, even if the disc is copy-protected. In some other countries, circumventing copy protection is illegal regardless of whether you own the disc. Check your local laws before proceeding.

How long do copied DVDs last?

Recordable DVDs typically remain readable for five to ten years, though this varies widely by brand and storage conditions. Keeping them in a cool, dry place away from direct sunlight extends their lifespan. For backups you need to keep longer, use an external hard drive instead.

What is the difference between DVD-R and DVD+R?

They are two competing formats that work almost identically. Most modern drives support both. DVD-R is slightly more compatible with older DVD players, but the difference is usually not noticeable. Buy whichever is cheaper.

Can I copy a Blu-ray disc the same way?

No. Blu-ray discs hold much more data and require different hardware and software. You would need a Blu-ray drive (not just a DVD drive) and Blu-ray-specific copying software. The process is similar but not interchangeable.
