Is Blu-Ray better than DVD?

Q What's so good about Blu-Ray? Should I be buying Blu-Ray discs instead of DVDs now?
Helen Martin, Sheffield

A Blu-Ray is better than DVD. But all the technical details come down to this: Blu-Ray discs can hold more data than DVDs - typically up to six times as much. And that extra room means Blu-Ray can carry high-definition releases, such as the HD version of Torchwood. So Blu-Ray will always be the better buy for picture quality.

But it's also more expensive. Prices are falling, but a Blu-Ray player still costs about £190, while you can pick up a DVD player for £40. (But a Blu-Ray player will also play DVDs and even CDs, too.)

Film and TV releases cost more on Blu-Ray, though, which is a downside when you can download films and TV shows cheaply to your PC. The picture quality on services like iTunes, good as it is, can't compare with the superior-looking Blu-Ray - but the convenience and improving picture quality still give downloading the edge.
