hey people! ever heard of sony's blu ray discs?? if not then i have a bit of information to share, i hope others can add on it.
What is a Blu-ray Disc?
A current, single-sided, standard DVD can hold 4.7 GB (gigabytes) of information. That's about the size of an average two-hour, standard-definition movie with a few extra features. But a high-definition movie, which has a much clearer image, takes up about five times more bandwidth and therefore requires a disc with about five times more storage. As TV sets and movie studios make the move to high definition, consumers are going to need playback systems with a lot more storage capacity.



Blu-ray is the next-generation digital video disc. It can record, store and play back high-definition video and digital audio, as well as computer data. The advantage to Blu-ray is the sheer amount of information it can hold:

A single-layer Blu-ray disc, which is roughly the same size as a DVD, can hold up to 27 GB of data -- that's more than two hours of high-definition video or about 13 hours of standard video.
A double-layer Blu-ray disc can store up to 50 GB, enough to hold about 4.5 hours of high-definition video or more than 20 hours of standard video. And there are even plans in the works to develop a disc with twice that amount of storage.

How about reading all the stickies and announcements through before posting, it's a good habit and will save you undue embarassment and/or banning in some cases.

There is a rule about plagiarism, and it means you have to specify the source of your text. It would also be nice if you could maybe add an opinion of your own as well that could be discussed.
Posting random articles won't get you far.
