I was looking at a DVD player on the internet and read in the description: The DVP642 plays standard DVDs as well as........
I didn't know a "standard" DVD existed yet. Can someone explain this?
Is DVD-R standard or is DVD+R standard? Or are they both considered standard?
How can the industry have two different standards?
This is very confusing to say it plays STANDARD DVD's and then when I drill down to more specs it says it plays DVD+R/RW. I don't think DVD+R is the "standard" DVD....at least not yet.
What's up with this?

A standard DVD is a commercial DVD movie--the kind you would buy or rent at a store. This type of DVD is called a DVD-ROM (Read-Only Memory). A DVD-ROM is written to by physically pressing a blank DVD-ROM against a mold that has the reverse of the grooves on the finished disc formed onto it (the same way commercial audio CDs are made). All DVD players support DVD-ROMs.
DVD-R/RW and DVD+R/RW are formats of recordable DVDs. Both types are written to by using a laser to “burn” grooves into the blank disc. Between the recordable DVD formats, there is no real standard; some DVD players support DVD-R/RW, some support DVD+R/RW, some support both, some support neither, and a few support all--including DVD-RAM (Random Access Memory).
As for the first answer: double-sided and dual-layer are two separate things. A DVD can be either or both. A double-sided DVD can even be single-layer on one side and dual-layer on the other (known as multi-layer or DVD-14).

in early DVD ages there was only DVD-R
DVD-R means that it has basic type of format to hold 4.7 GB of data. Then few years later some other lab develope DVD+R which is different kind of FORMAT then -R. now there is DUAL LAYER DVD-RDL and DVD+RDL.
They say that -R are good for VIDEO DATA and +R is better for normal DATA...

standard = original single sided format.
dual layer = new double sided
