I have seen some DVDs containing more than 7 GigaBytes of data when the Video_ts folder is copied to the hard disk. Now if I try to write them back into a blank DVD, the writing software (Nero in my case) claims that there is not enough space on that blank DVD. How those DVDs are written? Do they require spacial burner or software?

Hi, Sharful.

In terms of capacity, there are 2 kinds of DVDs: Single layer, also called DVD-5 because they hold 4.something GB, and double layer, AKA DVD-9 because they hold 8.something (this is what happens when marketing people make these decisions). The vast marjority or commerically-made discs are DVD-9s, and can hold more than 8GB. But the vast majority of blank discs are DVD-5s.

Some drives can burn dual-layer DVDs, but not all. And blank, burnable DVD-9s are, last I checked, much more expensive.

Hi Linkoln

Thanks for your answer. Now I'll be looking for DVD-9s.:D

Great. But just be sure your drive supports them--not just for reading (which they all do), but for writing.

Yes. My SAMSUNG burner supports among many other formats, dual layer burning. But i checked the market price of the blank dual layers and found them seven times higher priced than normal dvd. Now i must do feasibility study before writing onto them!
