- Blu-ray has been designed to be backwardly compatible.
- It should be able to play Blu-ray, DVD and CDs.
- HD-DVD was a separate format. These discs will not work in a Blu-ray player.
- Blu-ray players can "upscale" the signal from your DVDs, making them look better on an HD TV.
- You may need to upgrade your machine’s firmware to properly play Blu-ray 3D discs.
- Blu-ray 3D discs need a 3D TV to work fully. They will not produce a 3D effect on an ordinary television.
While Blu-ray players can play DVDs, they might be unable to play discs that are region locked to another country. For example, if you had a multi-region DVD and bought a lot of discs from America you may find these won’t work on your Blu-ray.
While there may be individual exceptions, regular DVDs should play fine on a new Blu-ray machine; you can upgrade safe in the knowledge that your existing collection will still work in your home cinema.
Always refer to the manufacturer’s manual for specific details.
