please excuse me for not knowing, but can someone please tell me the difference between DVD+R and DVD-R? some in depth detail would be appreciated. thanks.
 
says something about multi layer in +R vs single layer in -R. does this mean that i cant do dual layer burning on a DVD-R, but only DVD+R to burn in double the capacity?

Yes and only on a double layer disk. You can still burn single layer disks on DVD-R & DVD+R, but you can only burn the dual layer disks on DVD+R.I hope I didn't confuse you too much.

so let me get this straight, despite the fact that dvd-r is more widely supported and compatible with dvd players, they can not be burned in as dual layer even with a dual layer capable burner. dvd+r on the other hand, though not as widely supported, are able to be burned in dual layer with a capable burner (raising the capacity to almost 9 gigs?) ... those are the only differences right?

Edit: asdf, after looking at your post more carefully, another thought sprung into my head. so you can ONLY use dual layer burning methods from DL dvd burners to burn on DL disks? and they have to be +R? man im deeply confused.
 
Let me start from the beginning... the original recordable DVD standard was DVD-R, developed by Pioneer and Matsushita. It's website is here:http://www.dvdforum.org/forum.shtml , and the -R DL format has been developed, will come out in 1Q2005. The second recordable DVD format is DVD+R/RW, developed by Philips and Ricoh, whose website is the DVD+RW Alliance, website : http://www.dvdrw.com/ They have developed +R DL, which is the only double layer recordable DVD format out right now.

Clear?

I will be waiting for DL -R because +R just plain sucks

-R is now the movie industry standard for DVDs and i doubt regular dvd players or game systems will move to +R readers
You will get nothing but messed up screens when bancking up DVDs on +R.

They are good just for DATA period.

I would stick with -R and get a nnice sony or pioneer dvd drive when it comes out
 
Welp, the fun has just begun. This year you will see two new formats competing for your money. You have Blue-Ray and HD-DVD. Neither format can “see” the other and there is some question about backwards compatibility with your current DVD collection. Supposedly Blue-Ray will read DVD but HD-DVD will or can have more then twice the capacity. Sony and Toshiba are going to be in the big fight over this one.

I think you got it backwards. All of the current optical standards use a red laser, whereas BluRay (as the name suggests) uses blue (for all you physics people: shorter wavelength, higher frequency/energy). There are a couple of projects out there to develop multi-format discs and readers, and they seem to be working so far. However, backwaards-compatibility is not mandated, so choose your players and media carefully.

In short: BluRay is not guaranteed to read any other format, whereas HD-DVD should be able to read older discs- at least one of the two, and more likely "minus."

We wont see those to be practical until 2007

Even though it will be out in 2006 i doubt it will worth the money to upgrade . The drive will probbly take 30min or more to make one dvd and one dvd will cost like 3-5 dollars a pop.

I think dual layer dvd-r will come around in the middle of 2005 and we will be using them instead of 4.7 gig dvds. And they will be realitvly cheap

I think you're referring to currently available +R DL media -> they cost 3-5 dollars a pop right now, and take 25-40 minutes to burn.

Dual Layer DVD-R IS a 4.7GB DVD. It is coming next month or so, and they WILL NOT be relatively cheap.

Both machines are for sale now in Japan; we should see them by Christmas if not before. In fact they were actually supposed to hit this year.

As for “users” being able to write to them…well…talk to congress. Hollywood is the big hold up now.
 
yeah ok, then explain why my dvd player can read dvd+r's just fine.

I have read a article on this recently and DVD+R is better than DVD-R due to a better set of specifications to prevent reading errors and write errors. DVD-R is more sensitive to errors but is also more easy to read on DVD players. However, with the latest DVD readers, it should not be a real issue which one to pick. I would pick DVD+R because my player doesn't have a problem reading it.
