Question

What is difference between DVDs and DVD-R/+R?

Answer 1

DVD is a pre-recorded disk.

DVD - R  is a DVD that  you can write to, but the data on it can't be erased.

DVD -RW is a rewritable disk.  Where the data you have written can be deleted or overwritten.

Both types you can add more data if you have not closed the session.

DVD + R  and +RW  are the same basically.

- is more common than +  but they are different and not all DVD CD burners will support + format.

Answer 5

Hi Irfan,

The DVD+R and DVD-R are competing formats much like the old VHS and Beta formats in video tapes. Today most drives are Hybrid and handle both formats. They are usually labeled DVD+/-R

The market for recordable DVD technology never settled down in favor of either the plus or dash formats, which is mostly the result of the increasing numbers of dual-format devices that can record to both formats; it has become very difficult to find new devices that can only record to one of the formats. However, because the DVD-R format has been in use since 1997, it has had a five-year lead on DVD+R. As such, older or cheaper DVD players (up to 2004 vintage) are more likely to favor the DVD-R standard exclusively, and when creating DVD’s for distribution (where the playing unit is unknown or older) the DVD-R format would normally be preferable.

My personal experience has led me towards using the +R. It is slightly better at error handling so more tolerant of dirty or damaged media and also more tolerant to the subtle differences between players.
