Frequently asked questions about blu-ray duplication
Blu-ray, what is it?
Blu-ray is the replacement optical disc format for DVD video. The format has been specifically designed for the recording and playback of high definition video. Additionally, the format can be used as a high capacity storage disc, for data backup. (25gb or 50gb).
Are there any differences between blu-ray duplication and blu-ray replication?
Yes there are. The difference lies in the manufacturing process. With replication, usually minimum quantity of 500, a glass-master and stamper are made; these are then used in the 'pressing' of the discs, similar to an injection moulding process. With duplication, blank BD-R's are used, and the content is written, or 'burnt' onto the blank media. There is no difference in the final video or audio quality.
How much data can a blu-ray disc store?
Currently there are two capacities for blu-ray disc, this is 25gb, known as BD25 and 50gb known as BD50. BD50 represents a 10 fold increase in storage capacity, when compared to a standard DVD5.
How does the blu-ray storage capacity convert to actual video length?
A 50GB blu-ray disc, (BD50) can hold over 9 hours of high definition video, or roughly 23 hours of standard definition.

Blu-ray offers several advantages. More capacity, support for pop-up menus. This allows video settings to bechanged whilst watching the movie. Blu-ray also allows for internet and network connectivity. Further the blu-ray disc is harder wearing with a special polymer coating for more protection from scratches and general wear and tear.
Can CDs and DVDs play on a blu-ray player?
Currently there is no requirement for manufacturers to support backwards compatibility for CD and DVD, however most players do have support for this as default as it makes the player more desirable. It is always better to check each manufacturer's blu-ray player product specifications, as this will vary player to player.
Most Blu-ray players however, will include backwards playability compatibility for CDs and DVDs. A lot of players offer upscaling to 1080i / 1080p for DVD, this means you DVD video will look better on viewing through a blu-ray player.
